Other Parts Discussed in Thread: BQ76972
Tool/software:
Hi
We are planning to use stacked BQ76972 per TIDA-010247 in battery swappable modules that can be paralleled on a common DC bus.
In our case, when one module turns DSG OFF, the PACK bus might stay high (since other modules remain connected). This means PACK+ does not necessarily decreases.
- To be able to control de DSG FETs OFF. Is it acceptable to tie TOP_LD to UP_GND so the FET is actually turned off, driving the BOT_DDSG from MCU to turn on Q47.
- Could this cause any additional concerns for DSG turn-off in a live parallel bus ?
- can we have an schematic revision?
Thanks
