0V Battery Charging Function
(1) (2) (3)
This function enables the charging of a connected battery whose voltage is 0 V by self-discharge. When a
charger having 0 V battery start charging charger voltage (V0CHA) or higher is connected between EB+ and
EB- pins, the charging control FET gate is fixed to VDD potential. When the voltage between the gate and
the source of the charging control FET becomes equal to or higher than the turn-on voltage by the charger
voltage, the charging control FET is turned on to start charging. At this time, the discharging control FET is
off and the charging current flows through the internal parasitic diode in the discharging control FET. If the
battery voltage becomes equal to or higher than the overdischarge release voltage (VDU), the normal
condition returns.
0V Battery Charge Inhibiting Function
(1) (3)
This function forbids the charging of a connected battery which is short-circuited internally (0V battery).
When the battery voltage becomes 0.9 V (typ.) or lower, the charging control FET gate is fixed to EB-
potential to forbid charging. Charging can be performed, when the battery voltage is the 0 V battery charge
inhibiting voltage (V0INH) or higher.
(1) Some battery providers do not recommend charging of completely discharged batteries. Please refer to battery
providers before the selection of 0 V battery charging function.
(2) The 0V battery charging function has higher priority than the abnormal charge current detection function.
Consequently, a product with the 0 V battery charging function charges a battery and abnormal charge current
cannot be detected during the battery voltage is low (at most 1.8 V or lower).
(3) When a battery is connected to the IC for the first time, the IC may not enter the normal condition in which
discharging is possible. In this case, set the VM pin voltage equal to the VSS voltage (short the VM and VSS pins or
connect a charger) to enter the normal condition.
