Core Functions

1. 4 battery protection strings

• Support4S in SeriesLithium-ion/Lithium-polymer battery packs, single cell voltage range:2.5V–4.35V。

1. Adjustable Overcurrent Protection

• Flexible setting via external resistanceOvercurrent threshold for charging/dischargingAdaptable to various load requirements.

1. Temperature Protection and Compensation

• Built-in high and low temperature protection function, supports external thermistor to adjust temperature thresholds (such as)-20°C~60°CAdjustable).

1. High-precision voltage monitoring

• Real-time monitoring of each cell's voltage to prevent overcharge (OVP) and over-discharge (UVP), accuracy up to±25mV。

1. Low-power design

• Very low standby current (typical value)<3μA), suitable for portable devices.

1. Fault Indicator

• ThroughSTAT pinOutput abnormal conditions (such as overvoltage, undervoltage, overheating).
