(charge termination detect time), the ic enters stand-by mode. a driver transistor turns off during the stand-by mode. in this state, a failure detection circuit and a monitoring circuit of the battery pin voltage operates. (*1) the detect after charging completed: i sen pin voltage should be less than 100mv. in stand-by mode battery voltage falls. when the voltage level at the battery pin drops to recharge battery threshold voltage (typ. 4.05v) or less, the charge cycle automatically re-starts a fter a delay of (typ. 2ms). as such, no external activation control is needed. charge cycle (charge main routine) trickle charge constant-current charge (cc) constant-voltage charge (cv) ye s keeping the charge state during a charge termination detect time (1ms) charge termination (stand-by mode) ye s keeping the stand-by mode during a recharge time (2ms) failure detection input voltage monitor (uvlo) manual shut-down v in -bat voltage monitor charge cycle charge cycle charge cycle shut-down shut-down shut-down
6/21 xc6802 series operational explanation (continued) the /chg pin constantly monitors the charge states classified as below: ? strong pull-down: i /chg =10ma (typ.) in a charge cycle, ? weak pull-down: i /chg =20 a (typ.) in a stand-by mode, ? high impedance: in shutdown mode. even if the bat pin is shorted to the v ss , a trickle charge mode starts to operate for protecting the ic from destruction caused by over current. the uvlo circuit keeps the charger in shut-down mode until the input voltage, v in , rises more than the uvlo voltage. moreover, in order to protect the battery charger, the uvlo circuit keeps the charger in shut-down mode when a voltage between the input pin voltage and bat pin voltage falls to less t han 30mv (typ.). the charge will not restart until the voltag e between the input pin voltage and bat pin voltage rises more t han 100mv (typ.). during the shut-down mode, the driver transistor turns off but a failure detection circuit operates, and supply current is reduced to 10 a (typ.). to protect against inrush current from the input to the batte ry, soft-start time is set in the circuit optimally (150 s, typ.). during the charge cycle, the ic can be shif ted to the shut-down mode by floating the i sen pin. for this, a drain current to the battery is reduced to less than 2 a and a shut-down current of the ic is reduced to less than 10 a (typ.). a new charge cycle starts when reconnecting the current sense resistor. when the bat pin is left open, the ic needs to be shut-down once after monitoring the chg pin by a microprocessor etc and keeping the i sen pin in h level. a backflow prevention circuit protects against current flowing from the bat pin to the v in pin even the bat pin voltage is higher than the v in pin voltage. 4.20v 4.05v 2.9v cc cv trickle standby recharge battery time (2ms, typ) recharge battery voltage i bat /10 charge current i bat battery termination detect time (1ms, typ) /chg pin status weak pull down (20ua, typ) strong pull down (10ma, typ) strong pull down (10ma, typ)
