Part Number: BQ76PL455A

I use the MCU sent Passive Balance message ：1、 0x91 0x00 0x13 0x08+2 CRC 2、0x91 0x00 0x1f 0x00 +2 CRC 3、 0x92 0x00 0x14 0xff 0xff +2 CRC，toBQ76PL455A-Q1， THE device is not reply. the communication is normal , if the message is wrong ? could you offer some application note about enable Passive balance ,many thanks ~

there some question：1. if i use bq76pl455a monitor Battery 4s ,if the device could work nromal? 2. if there is a battery voltage lower than 1V, is there any affect about balance and the other battery monitor ?

You must have at least 6cell and 12V min voltage.
You have to check the Vgs of your FET and make sure your cell voltage is higher than Vgs of FET you using.
If not then you can not turn the FET on.
