Over-voltage watchdog for 2-4 series Li-ion packs
The BQ296224DSGT monitors 2 to 4 series-connected lithium-ion cells and triggers a fault output when any cell exceeds the over-voltage threshold. This is the core protection function in a battery pack — catching a cell that drifts high during charging before it reaches an unsafe voltage. The 8-WSON (2x2 mm) package with exposed pad keeps the thermal path short to the PCB copper pour.
Package and board-fit — 8-WSON with exposed pad
Surface-mount assembly with the pad soldered to a PCB thermal land — the datasheet's recommended footprint keeps the junction temperature within the -40°C to 110°C operating range. Cut Tape works for prototype or low-volume repair kits.
