  在快速发展的TWS和智能穿戴市场,受限于产品的体积,锂电池的容量通常都比较小(40mAh到500mAh)。为了更好的延长使用时间,需要利用电源分配开关,关闭一些待机时不用的功能,降低待机电流,从而实现延长电池使用时间的目的。

  APM(应能微电子)推出的APL0501是一款超小封装,低输入电源电压,低导通电阻负载功率开关,采用先进的BCD工艺,量产出超低功耗的产品,满足智能消费产品中锂电管理的苛刻要求。

  APL0501是由外部使能管脚(ON)控制的低导通电阻MOSFET开关,可优化电池寿命和便携式设备自主功能。内部结构为P-MOSFET +N-MOSFET,工作电压在1.2V到5.5V。ON/OFF输入(ON)控制开关,可以与各种低控制电压信号接口相连。片内集成典型值130欧姆输出下拉电阻,当芯片被关断时,下拉开关闭合实现输出快速放电,起到抑制倒灌电流IREV的功能。
