- Full Refund if you don't receive your order
Outline
This IC was developed for use in controlling charging and discharging of
lithium ion batteries (battery modules
with three cells connected in series). In charging control, the voltage of the
battery module as a whole is controlled in constant-voltage control. Discharge
control and monitoring of overvoltage rely on monitoring of
the voltages of individual cells.
Features
1. Charging control voltage VBATH=12.465V±1.5% (Ta=-20°C~70°C)
2. Overcharge detection voltage VCELL=4.335V±1.5% (Ta=-20°C~70°C)
3. Internal circuit for setting dead time (for overvoltage detection,
discharge control)
4. Low consumption current on overdischarge IBATH3=1µA typ.
5. High-precision internal overvoltage detection startup circuit (cell
voltage 4.2V or higher at end of charging)
