通过I2C总线通讯读写芯片数据,通讯时钟频率可达400KHz。 可以通过存储IC的型号来计算芯片的存储容量是多大,比如24C02后面的02表示的是可存储2Kbit的数据,转换为字节的存储量为21024/8 = 256byte;比如24C04后面的04表示的是可存储4Kbit的数据,转换为字节的储存量为41024/8 = 512byte;以此来类推其它型号的存储空间...
IC在第9个周期未给出ACK。在第9个周期内,SDA线未拉低。之前提过相同的问题:https://e2e.ti.com/support/power-management/f/196/t/323329,但未指出解决方案或原因。我更换了BMS IC,但问题仍未解决。 我已研究了http://www.ti.com/lit/zip/sluc583和应用注释http://www.ti.com/lit/pdf/slva626...

This function can be disabled by setting BATFET_RST_EN bit to 0. nQON PIN OPERATION Internally, there is a 500K pull up resistor from nQON pin to VDD(maximum of VBAT and VLDO).So default, nQON will be high. Then nQON logic low and high voltage threshold are 0.68V and 0.88V ...
Any short on PMIDU will damage the IC. USB Source Detection Input – Drive PSEL high to indicate that a USB source is connected to the USB input. When PSEL is high, the IC starts up with a 100mA (bq24161/8) or 500mA (bq24161B) input current limit for USB. Drive PSEL low ...

I'm having trouble writing to BQ registers. The IC doesn't give an ACK on the 9th cycle. The SDA line isn't pulled LOW during the 9th cycle. The same issue had been brought up earlier https://e2e.ti.com/support/power-management/f/196/t/323329 But neither the solution nor the ...
