AW32207FCR中文资料Li-Ion battery charge management chip数据手册Awinic规格书

描述 Description

AW32207 is a high efficiency, large current，switch- mode Li-Ion battery charge management chip. The chip integrates 1.5 MHz synchronous Buck PWM controller, Boost PWM controller and power MOSFETs, effectively reducing the power loss.The charge process of AW32207 includes: trickle, constant current (CC) and constant voltage (CV). The charge parameters and operating modes are programmable through I2C Interface. Also, the charge termination is determined by a programmable algorithm. The charge process runs automatically and recharging occurs when the battery voltage drops below VOREG-VRCH.
