专用于电源恒压恒流的控制器ME4313,内置1.21V精密电压基准,供电电流低至0.5mA
ME4313是微盟电子研发的专用于电源恒压恒流的控制器,可应用于适配器/充电器等。
ME4313产品特点
恒压恒流控制
精密内部电压基准
低供电电流:0.5mA
电源Vcc电压工作范围2.5-18V
外围精简,省略431基准源
ME4313原理图
从上图可以看出该ME4313的应用原理其实并不复杂,在设计上也是较为精简。
(1)输出电压计算公式
(2)限流计算公式
ME4313应用方案
ME4313采用的是SOT23-6封装,外围精简元器件少,可以更好的节约BOM成本。
下面将通过实验体现数据来对比一下ME4313的应用场合
实验条件
室温
前端主控芯片非恒流/恒功率芯片
实验过程
1、不加ME4313
如图,没有加ME4313,可以看到电源被拉过流保护,导致设备一直断充,长期这样工作的严重还会损坏电源设备
2、加入ME4313
如图,设计方案时加入ME4313,可以清晰的看到,ME4313进入恒流工作模式,有效的保护电源和设备在正常工作状态下。
经过以上实验测试,可以清楚的看到ME4313发挥着极大恒流/恒压作用,能够有效的保护电源芯片不会被拉保护,从而能更好的保护电源和用电设备。
ME4313总结
ME4313包含一个1%精度的1.21V电压基准(在部分电源中可省略传统的431基准源,同时节约BOM成本),两个运算放大器,一个作为电流传感器,另一个作为电压控制器。将基准电压与运算放大器相结合,使ME4313成为输出低侧电流检测的理想限流器。

【应用】零功耗使能降压DCDC电源芯片EG1192H用于两轮车控制器中,可解决96V电摩兼容设计问题
在两轮车电控方面,通常会做一款兼容设计,这就使得在电控上对一级电源的要求比较高,目前96V的应用中,通常需要120V的一级电源作为前级输入,并且需要比较大的电流,通常为1.5A/2A。零功耗使能降压DCDC电源芯片EG1192H作为宽压DC-DC,满足120V输入的要求,并且可以输出5V/1.5A的电压、电流。
