bq25895读不到电流,REG12=0x00

Other Parts Discussed in Thread: BQ25895

以下是我的寄存器值:

我用bq25895对三节并联的18650充电,

REG00=0x7F,
REG01=0x05,
REG02=0x7B,
REG03=0x3A,
REG04=0x9F,
REG05=0xF3,
REG06=0x5E,
REG07=0x04,
REG08=0x03,
REG09=0x44,
REG0A=0x93,
REG0B=0x76,
REG0C=0x00,
REG0D=0x13,
REG0E=0x48,
REG0F=0x47,
REG10=0x3E,
REG11=0x95,
REG12=0x00,
REG13=0x3F,
REG14=0x39,

1. 我的VBAT是3.7。VBAT  >  VBATSHORT满足要求

2. REG0C=0x00,说明bq25895无异常。 

3. 我也参考了https://e2e.ti.com/support/power-management/f/196/p/719227/2653042?tisearch=e2e-sitesearch&keymatch=bq25895%20REG12%200#2653042。  

 VSYS是有负载的,不是空载。

4. REG0B=0x76, 表示 usb dcp模式,  Fast Charging模式,进入了充电模式的。

 请问为啥ADC采集不到充电电流?
