Bq40370

The BQ40370 integrates multiple functions to ensure battery safety and reliability. Its core capabilities include:

It controls the charging FETs (Field-Effect Transistors) based on internal parameters and communication with the laptop's motherboard. Why Do BQ40370 Batteries Fail? bq40370

: The core algorithm determines remaining battery capacity based on modeling the battery’s voltage discharge curve under varying loads and temperatures. It uses pre-programmed voltage trip points (EDV0, EDV1, EDV2) to dynamically adjust when the battery is nearing zero capacity. The BQ40370 integrates multiple functions to ensure battery

The BQ40370 often enters a "locked" state or triggers a Permanent Failure Flag (PFF) if it detects a cell imbalance or if the battery cells are disconnected during a repair. bq40370
