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. If the VM terminal voltage is higher than the charge over-current detection voltage (VIc), the IC
returns to the normal condition when VDD becomes equal to or higher than VRdc and this state continues more than the
delay time1 (trel1).
If the VM terminal voltage is lower than the charge over-current detection voltage (VIc), same as the above-mentioned
case, the IC returns to the normal condition when VDD becomes equal to or higher than Vdc and this state continues
more than the delay time1 (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)
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.
