Other Parts Discussed in Thread: BQ76930
Hi everyone,
I'm a hardware engineer and I from Viet Nam. I am following a BMS project management 20 cells pin and I am using BQ76940 IC. I read reference design BQ76930 of TI. I saw ALERT pin of AFE Upper connect with MCU via FET and some resistors, diodes. Why not use opto isolate the same as I2C interface. Please help me. Thanks.
