Charger

概述

WQ7036 支持用于锂电池的集成充电器。支持的充电电流可编程为 0 mA 至 360 mA。

内置电池电流监控器和比较器。目标低电压、目标满电压、充电器电流在不同模式下可编程。

用户可以灵活使用各种锂电池和充电策略。如果在规定的时间段内电池行为异常，充电过程将停止以保护电池。

功能特性

Charger 典型的充电模式有四种：涓流充电模式、恒流模式、恒压模式和重新充电模式。

资源依赖

CHARGER
ADC

用法流程

初始化 wq_charger_init()
设置充电电压 wq_charger_set_voltage()
设置充电电流 wq_charger_set_current()
配置模式 wq_charger_set_gpio_mode()
