Working Principles

BQ294707DSGT operates by continuously monitoring the battery voltage and current. It compares these values with the set thresholds and triggers the appropriate protection mechanism when necessary. The device disconnects the battery from the load during overvoltage or undervoltage conditions, and interrupts the circuit in case of overcurrent. The fault indicator provides visual feedback on any protection event.
