描述 Description

ET95101 is a high performance devices for space limited portable applications highly integrated Li-Ion battery linear charger. The high input voltage range with input over-voltage protection supports low cost, non regulated adapters. The ET95101 has a power output that can charge the battery. If the average system load cannot fully charge the battery during the 10 hours security timer, you can parallel the system load with the battery.The battery charging goes through the following three stages: regulation(pre-charge), constant current(CC) and constant voltage(CV).In all charging stages, the internal control loop will monitor the IC junction temperature, and when it exceeds the internal temperature threshold, it will reduce the charging current.The charger power level and charging current sensing functions are fully integrated. The charger has high-precision current and voltage regulation loop and charging termination function. The charging current value can be programmed via an external resistor.
