Features
- Overcharge Protection: Activates when battery voltage exceeds 4.3V (±50mV), with automatic release at 4.1V (±50mV).
- Overdischarge Protection: Triggers below 2.4V (±100mV), releasing at 3.0V (±100mV).
- Overcurrent Protection: Detects currents above 150mV (±30mV), with short-circuit detection at 1.35V.
- Ultra-Low Quiescent Current: Consumes just 3µA (typical) at VCC = 3.6V, extending battery shelf life.
- Integrated Delay Circuits: No external capacitors needed for delay timing.
- Charge from 0V Battery: Supports charging of deeply discharged cells.
- Operating Temperature: -40°C to +85°C.
