Hi, I am using BQ76920 for 20S BMS. This chip will handle 5 upper cells. Here is the schematic of it:
I measured the voltage on C56 and C29 already (~1.6V) even the input voltage (A15, A16) are 3.44V (li-ion 18650 battery). I've booted the device by connect the pin TS1 to 3.44V via 10k resistor manually.
Is the chip damaged?
Thanks for your help!
