Over-discharge detection
When the battery voltage (VDD) under the normal condition becomes equal to or less than the over-discharge detection
voltage (Vdc) and that state continues for more than the over-discharge detection time (tdc), this IC turns off the
discharge control FET and stops discharging. This state is called the over-discharge detection condition. Recovery from
the over-discharge detection condition is achieved only by connecting the charger.
Return from over-discharge
When the charger is connected and charging starts, the charge current flows through the internal parasitic diode of the
discharge control FET. When VDD becomes higher than Vdc and that state continues for more than the delay time
1(trel1), this IC is released from the over-discharge detection condition automatically and returns to the normal
condition.
If VDD is less than Vdc, this IC returns to the normal condition when VDD becomes equal to or higher than Vdc, and
this state continues more than delay time 1 (trel1).
This IC stops all internal circuits (Shutdown condition) after detecting the over-discharge and reduces current
consumption. (Max 0.1
μA, at VDD = 1.8V)
Charge to 0V battery
0V battery charge function
If the voltage of charger (the voltage between VDD and VM) is larger than the 0V battery charge starting charger
voltage (Vcha), 0V battery charge becomes possible when CO terminal outputs VDD terminal potential and turns
on the charge control FET.
