Introduction

AI Translation

This chip is a fully integrated power management IC designed for Bluetooth charging cases, incorporating lithium battery charge management, a synchronous boost converter, battery fuel gauge, and protection function modules. It integrates an input overvoltage protection circuit with an overvoltage protection threshold of 6.1V, and the VIN input withstand voltage is up to 30V. The chip also integrates an adapter adaptive function to prevent no-charging or adapter damage scenarios. It supports automatic load detection, auto-shutdown mode, and 5V always-on output mode. In auto-shutdown mode, the default standby voltage is 2V; alternatively, the standby voltage can be set to the battery voltage by connecting a pull-up resistor from BAT to the OUT pin. The standby current in auto-shutdown mode is 4.5uA, and the chip standby current in 5V always-on output mode is 45uA.
