Bq40370 Hot! Page

FETs are N-channel MOSFETs, driven with ~10V gate drive (from internal charge pump).

It is an ACEDV (Advanced Compensated End-of-Discharge Voltage) gauge. bq40370

: The chip is usually password-locked (sealed) to prevent tampering. Unsealing is the first step to editing parameters. FETs are N-channel MOSFETs, driven with ~10V gate

: The bq40370 is programmable; firmware updates or resets are often necessary when "re-packing" battery cells to clear error flags (like "Permanent Failure") that prevent the battery from charging. Common Use Cases Battery Repair FETs are N-channel MOSFETs

Would you like a sample CEDV configuration spreadsheet or an example I²C register read/write sequence in C?

: If the battery provides zero voltage, the thermal fuse may be blown. It is typically located under the sticker near the battery connector.
