BQ24020 bqTINY-II 单片 1 节锂离子充电器,具有 USB/AC 电源管理、采用 3x3mm2 QFN 封装并具有使能端和温度传感器

BQ24020 描述

The bqTINY-II series are highly-integrated, flexible Li-Ion linear charge and system power management devices for space-limited charger applications. In a single monolithic device, the bqTINY-II offers integrated USB-port and ac-adapter supply management with autonomous power-source selection, power-FET and current-sensor interfaces, high-accuracy current and voltage regulation, charge status, and charge termination. The bqTINY-II automatically selects the USB-port or the ac-adapter as the power source for the system. In the USB configuration, the host can select from two preset charge rates of 100 mA or 500 mA. In the ac-adapter configuration, an external resistor sets the system or charge current. The bqTINY-II charges the battery in three phases: conditioning, constant current, and constant voltage
