| data sheet single-cell li-ion charger ic wi th system power management aur9807 nov. 2011 rev. 1. 0 bcd semiconductor manufacturing limited 1 general description the aur9807 is a single-cell li-ion charger ic with system power management feature. it charges the battery and power the system simultaneously. the maximum charging current (up to 1.5a) is set by external resistor for fast charging. the output voltage for the system is regulated to a nominal value (three different versions available: 4.4v, 5v or 6v); the actual value of the output voltage depends on the input voltage from the adapter, the charging current and the system loading. with the decrease of the input voltage or the increase of the system loading current, the output voltage drops. when the output voltage drops to a predetermined value (v apm-reg ), the active power management function is activated and tries to maintain the output voltage at v apm-reg ; the aur9807 will suffice the system loading with first priority and reduce the charging current temporarily, i.e. under heavy load condition, the aur9807 charges the battery with the remaining available current to keep the output voltage at v apm . in this manner, the charge and discharge cycle of the battery can be reduced. it is possible that the aur9807 fails to maintain the output voltage at v apm-reg ; for example, when the system loading current exceeds the capability of the current-limiting ac adapter. in this scenario, the output voltage drops to the battery voltage, and the system is allowed to draw current from the battery. the aur9807 is available in qfn-4.53.5-20 package. features ? qfn package ? active power management (apm) for simultaneously powering the system and charging the battery ? total current supported up to 2 amperes (system loading having higher priority on the budget) ? automatic power source selection (ac adapter or battery) ? 40m ? power path for the battery to supply the system power efficiently ? junction temperature detection and thermal regulation during charging process ? external led indicating charger and power good status as well as fault condition ? thermal, short-circuit, and reverse current protection ? short-circuit protection in the low power consumption sleep mode ? sysoff function to cut off the path between the system and the battery ? built-in over voltage protection up to 18v applications ? battery-powered devices or equipment ? mobile phones, digital cameras and mp3 players ? radios, other hand-held games and instruments ? solar power system figure 1. package type of aur9807 qfn-4.53.5-20

(3) ; all these guarantee a high efficiency and elongate the battery discharge time. with this stringent sleep current budget (<5a), the aur9807 is still able to detect an output short condition and cuts off the power path between the battery and the system under short condition. with the input power present, the mode pin sets the aur9807 in adapter mode or usb mode. in adapter mode, the aur9807 does not limit the total current directly, current limiting phenomenon occurs through adaptive power management in response to the output voltage drop. the resistor connected to iset1 pin sets the maximum charging current. this maximum charging current can be halved by pulling down the iset2 pin. in usb mode, the aur9807 will limit the total current within 450ma (iset2=high) or 90ma (iset2=low). the maximum charging current is still set by the resistor connected to iset1 pin; however, because of this current limiting feature, the actual charging current is usually less than 450ma (or 90ma).

system power management aur9807 nov. 2011 rev. 1. 0 bcd semiconductor manufacturing limited 16 charge function descriptions (continued) the maximum charging current, the pre-charge current and charge done current setting are given in the above table. the charging process begins with a pre-charge phase; when the battery voltage reaches the pre-charge threshold v lowv , the charger enters the constant current mode. at this stage, the charger tries to charge the battery with the maximum charging current (a constant); however, the actual charging current may be lower due to active power management activated by large system loading or insufficient input current capability. the thermal fold-back mechanism al so reduces the actual charging current when the junction temperature is over 110c. the battery voltage rises gradually with the constant current entering the battery. when the battery voltage reaches v bat(reg) , the charger enters the constant voltage mode. at this stage, the charger keeps the battery voltage at v bat(reg) with a decreasing char ging current. when the charging curr ent drops below the charge done current setting, nominally the charging process is complete (this can be observed from the external indicator). depending on different versions, after the charge done status indicated, the charger will stop providing charging current completely or stay in constant voltage mode till time out. when the battery voltage drops below the recharge threshold, a new charge cycle begins. example: with a r set =1k ? , the maximum charging current is about 1a for iset2=high and 0.5a for iset2=low. the pre-charge current i prechg is 100ma. the charge done current setting is 100ma for ac mode and 40ma for usb mode. note the absolute values of pre-charge current and charge done current setting do not vary with iset2. power source selecting out ref i. v in data sheet single-cell li-ion charger ic wi th system power management aur9807 nov. 2011 rev. 1. 0 bcd

apm-reg data sheet single-cell li-ion charger ic wi th system power management aur9807 nov. 2011 rev. 1. 0 bcd semiconductor manufacturing limited 18 charge function descriptions (continued) the aur9807 interrupts the charging process when the battery temperature is out of normal range. it provides a 100a sensing current to the negative-temperature coefficient resistor (on the battery side) through the ts pin. the battery protection is achieved by constantly monitoring the voltage at the ts pin. when this voltage is higher than v ltf (nominally 2.5v) or lower than v htf (nominally 0.5v), an under-temperature or over-temperature condition is detected. for an usual 103at-type ntc resistor, the corresponding temperature range is between 0c and 45c. the normal battery temperature range can be modified by adjusting the ntc resistor or by adding extra resistor network between the ts pin and the negative-temperature coefficient resistor. the charging process would resume after the battery temperature goes back within the normal range. charge timeout setting the charge timeout setting is programmed by the resistor r tmr connected between the tmr and ground pin. the timeout setting is given by: t chg = k tmr r tmr a suggested 36k ? r tmr gives a 3.6 hrs timeout setting because the nominal value of k tmr is 0.36 sec/ ? . in the actual charging process, the charging duration is elongated if the charging current can not reach the maximum current setting (again this relates to system loading and environment temperature); therefore, it is possible that the charging process is still on progress while the 3.6 hrs timeout limit has been reached. to circumvent this problem, the actual charging current is monitored and the clock rate of the timer counter is halved if the charging current is less than 50% of the maximum fast charging current. this is equivalent to modify the timeout setting temporarily by the following equation: t chg = k ext1 x k tmr r tmr , where k ext1 =2 if the actual charging current is less than one fourth the maximum fast charging current, the time out counter rate is reduced to 25%. the temporary timeout setting is given by: t chg = k ext2 x k tmr r tmr , where k ext2 =4 once the abnormal condition is removed (high temperature or heavy loading), the charging current resumes the maximum values (set by r set ), and the time out counter will operate in normal rate. charge status indicator status stat1 stat2 pre-charge on on constant current and constant voltage charge on off charge done off on fault condition (time out, sleep mode, or otp) off off the open drain pins stat1 and stat2 provides the information about the charger status when the ce pin (chip enable) is set to high. the various charger status and the corresponding stat1 and stat2 levels are given in the above table. connect these pins to the host processor or leds to indicate the charger status. short circuit protection aur9807 provides short circuit protection for both the input and the battery. when v in is larger than v bat , ac adapter (or usb port) is chosen as the power source. if the output voltage is lower than 1v (v out(sc1) ) for more than t dgl(sc) , a short circuit condition is detected; the power path between the input and the output will be cut off. the charging process will be interrupted. a 500 ? resistor is used to pull up the output voltage; if the load at the output is removed, the output voltage can be pulled up and the short circui t condition is dissolved. similarly, when the battery is chosen as the power source, an output voltage lo wer than the battery voltage by 200mv (v out(sc2) ) longer than t dgl(sc) will trigger the short circuit protection mechanism (this corresponds to a 5a loading current). a 10ma current source is used to pull up the output and detect the removal of the short condition. the power consumption is less than 5a under the battery supply mode; however, aur9807 is still able to monitor the output voltage and detect a short circuit condition with this limiting current budget. sysoff function the sysoff function is used to cut off the power path between the battery and the output. this means the data sheet single-cell li-ion charger ic wi th system power management aur9807 nov. 2011 rev. 1. 0 bcd semiconductor manufacturing limited 19 charge function descriptions (continued) charger function can be disabled by pulling up the sysoff pin; in this mode, the aur9807 is almost a regulator to power the system. because the power path is cut off, the output voltage will drop to zero when the input source is removed, the battery will not be used to power the system. the sysoff pin is pulled high internally; therefore, this pin should be pulled to ground for normal operation. recharge process and timer fault elimination if timeout occurs and the battery voltage is higher than the recharge threshold, the charger will stay in the charge done mode until the battery voltage drops below the recharge thre shold. once the battery voltage drops below the recharge threshold, a new charge cycle starts. if timeout occurs and the battery voltage is lower than the recharge threshold, the charger will indicate a fault condition and an internal resistor between output and battery will try to pull up the battery voltage. if the internal resistor is unable to pull up the battery voltage to the recharge threshold, the charger will stay in fault condition. once the battery voltage is higher than the recharge threshold, the charger removes the pull-up resistor, leaves the fault condition and stay in the charge done mode temporarily. the charger then waits the battery voltage to drop below the recharge threshold and starts a new charge cycle. data sheet single-cell li-ion charger ic wi th system power management aur9807 nov. 2011 rev. 1. 0 bcd semiconductor manufacturing limited 20 pc board layout considerations it is important to pay special attention to the pcb layout. the following provides some guidelines. 1. to obtain optimal performance, the decoupling capacitor from the input terminal to gnd and the output filter capacitor from out to gnd should be placed as close as possible to the aur9807, with short trace runs to both signal and gnd pins. 2. all low-current gnd connections should be kept separate from the high-current charge or discharge paths from the battery. use a single-point ground technique incorporating both the small signal ground path and the power ground path. 3. the high-current charge paths into in and from the bat and out pins must be sized appropriately for the maximum charge current in order to avoid voltage drops in these traces. v bat r6 100k r10 10k jp1 1 2 3 r13 /opt u1 aur9807 1 2 3 4 5 6 11 12 9
