Battery protection for 2-4 series Li-Ion packs
The BQ296113DSGT is a Texas Instruments battery protection IC designed to monitor and protect 2 to 4 series-connected lithium-ion cells against over-voltage conditions. Its -40°C to 110°C operating range covers the full industrial temperature band, so it suits packs in portable tools, power banks, and backup battery systems that see both cold storage and internal heat from charging.
Over-voltage detection and thermal envelope
The IC's fault protection is limited to over-voltage detection — it triggers when any cell in the stack exceeds the threshold, pulling the output low to signal the charger or system controller to stop charging.
