7 fn8093.3 august 9, 2011 pin description rst the push-pull rst output is set to v dd (high) whenever 1) the device is first powered up, 2) either v dd or the voltage on vmon falls below their respective minimum voltage sense levels, 3) mr is asserted or 4) the watchdog timeout expires. rst /mr this pin functions as both a reset output and a manual reset input. the rst output functions identically to the complementary rst output but is an open drain output that is pulled to gnd (low) when reset is asserted. the mr input is an active-low debounced input to which a user can connect a push-button to add manual reset capability or drive with active low signal from a controller. v dd the v dd pin is the power supply terminal. it is monitored by the isl88011, isl88012 and isl88013. for these devices, the voltage at this pin is compared against an internal factory-programmed voltage trip point, v thvdd . a reset is first asserted when the device is initially powered up to ensure that the power supply has stabilized. thereafter, reset is again asserted whenever v dd falls below v thvdd . the device is designed with hysteresis to help prevent chattering due to noise. vmon the vmon pin on the isl88012, isl88014 and isl88015 is a monitored input voltage that is user-adjustable. the voltage at this pin is compared against an internal 600mv reference voltage (v thvmon ) and a reset is asserted whenever the monitored voltage falls below this trip point. wdi the watchdog input takes an input from a microprocessor and ensures that it periodically toggles the wdi pin, otherwise the internal watchdog timer runs out and reset is asserted. the internal watchdog timer is cleared whenever the wdi input pin sees a rising or falling edge or the device is manually reset. c por the c por input pin lets users increase the power-on reset timeout delay (t por ) by connecting a capacitor between c por and ground.

8 fn8093.3 august 9, 2011 principles of operation the isl88011 through isl88015 devices provide those functions needed for critical voltage monitoring. these features include power-on reset control, customizable supply voltage supervision, watchdog timer capability, and manual reset assertion. by int egrating all of these features into a small 5 ld sot-23 package and using only 5.5a of supply current, the isl88011 through isl88015 devices can assist in lowering system cost, reducing board space requirements, and in creasing the reliab ility of a system. low voltage monitoring during normal operation, these supervisors monitor both the voltage level of v dd (isl88011, isl88012, isl88013) and/or vmon (isl88012, isl88014, isl88015). the device asserts a reset if any of these voltages falls below their respective trip points. the reset signal ef fectively prevents the system from operating during a power fa ilure or brownout condition. this reset signal re mains asserted until v dd and the voltage on vmon exceed their voltage threshold setting for the reset time delay period t por of 200ms (see figure 1). the isl88012, isl88014 and isl88015 allow users to customize the minimum voltage sense level on the vmon input pin. to do this, connect an external resistor divider network to the vmon pin in or der to set the trip point to some voltage above 600mv according to the following equation (see figure 2): figure 1. voltage moni toring timing diagram v dd vmon mr rst t por v thvdd 1v v thvmon t por t por t por >t mr t rpd t rpd rst v intrip 0.6 r 1 r 2 + () r 2 ------------------------- - = (eq. 1) isl88012 v in r 1 r 2 isl88014 isl88015 vmon figure 2. using vmon to monitor v in via resistors isl88011, isl88012, isl8 8013, isl88014, isl88015
9 fn8093.3 august 9, 2011 power-on reset (por) applying at least 1v to the v dd pin activates a por circuit which asserts reset (i.e., rst goes high while rst goes low). the reset signals remain asserted until the voltage at v dd and/or vmon rise above the minimum voltage sense level for time period t por . this ensures that the voltages have stabilized. these reset signals provide several benefits: ? it prevents the system microprocessor from starting to operate with insufficient voltage. ? it prevents the processor from operating prior to stabilization of the oscillator. ? it ensures that the monitored device is held out of operation until internal registers are properly loaded. ? it allows time for an fpga to download its configuration prior to initialization of the circuit. adjusting por timeout via c por pin on the isl88011 and isl88014, users can adjust the power-on reset timeout delay (t por ) up to many times the normal t por of 250ms. to do this, connect a capacitor between c por and ground (see figure 3). for example, connecting a 30pf capacitor to c por will increase t por from a typical 250ms to about 2.5s. note: care should be taken in pcb layout and capacitor placement in order to reduce stray capacitance as much as possible, which lengthens the t por timeout period. manual reset the manual reset input (mr ) allows the user to trigger a reset by using a push-button switch. the mr input is an active-low debounced input. by connecting a push-button directly from mr to ground, the designer adds manual system reset capability (see figu re 4). reset is asserted if the mr pin is pulled low to less than 100mv for 1 s or longer while the push-button is closed. after mr is released, the reset outputs remain asserted for t por (200ms) and then released. watchdog timer the watchdog timer circuit checks microprocessor activity by monitoring the wdi input pin. the microprocessor must periodically toggle the wdi pin within t wdt (1.6s nominal), otherwise the reset signal is asserted (see figure 5). internally, the 1.6s timer is cleared by either a reset or by toggling the wdi input. besides the 1.6s default timeout during normal operation, these devices also have a longer 51s timeout for start-up. during this time, a reset cannot be asserted due to the wdi not being toggled. the longer delay at power-on allows an operating system to boot, an fp ga to initialize, or the system software to initialize without the burden of dealing with the watchdog. symbol table 0 2 3 5 0 102030 c por (pf) t por (s) isl88011 c por isl88014 figure 3. adjusting t por with a capacitor 40 50 60 70 80 4 1 6 v dd rst /mr pb isl88012 r pu isl88013 isl88014 isl88015 isl88011 figure 4. connecting a manual reset push-button waveform inputs outputs must be steady will be steady may change from low to high will change from low to high may change from high to low will change from high to low don?t care: changes allowed changing: state not known n/a center line is high impedance isl88011, isl88012, isl8 8013, isl88014, isl88015
