【选型】国产双路型USB协议检测IC,可pin to pin 替代UC2632
随着目前手机充电器的多样化,一款充电器都需要适配多个手机,而每个手机的充电规格又不完全相同,因此为了能准确识别充电设备的充电规格,在每个充电器中都需要加入一个充电协议检测IC。
伊凡微的协议检测IC,AP5889,是一款双路型USB协议IC,可自动识别充电设备类型,并通过对应的USB充电协议与设备握手,使之获得最大充电电流,在保护充电设备的前提下节省充电时间。
目前市面上广泛使用的是USB协议IC,UC2632,AP5889可以直接pin to pin 替换使用,对比如下:

由封装对比可知,两者采用的都是SOT23-6封装,并且管脚都一一对应,因此可以直接pin to pin 替换。
另外在规格参数上,
国产双路型USB协议检测IC AP5889规格入下:
1、工作电压:4.5V~5.5V;
2、双端口控制功能:可同时独立支持两路USB充电协议检测;
3、支持多种USB充电协议,各充电协议自动切换,包括:Divider1/Divider2/Divider3充电协议(苹果专用),D+/D-置1.2V模式(三星专用),BC1.2 DCP及CTIS YD/T1591-2009充电协议;
4、可靠的上电复位(POR)及低电压复位(LVR)性能;
5、封装及脚位:SOT23-6。
UC2632的规格入下:
1、工作电压:4.5V~5.5V;
2、双端口控制功能:可同时独立支持两路USB充电协议检测;
3、支持苹果协议,2.1A/1.0A ,三星2.1A快充,DCP 1.0A;
4、封装及脚位:SOT23-6。
