It monitors each cell voltage and triggers a fault output if any cell exceeds the over-voltage threshold, providing a hardware safety layer independent of the primary fuel gauge or charger. The device is housed in a 6-WSON (2x2 mm) package with an exposed thermal pad, suited for space-constrained battery pack PCBs in portable electronics, power tools, and light electric vehicles. ## Over-voltage protection — what it covers and what it doesn't The BQ294502DRVR is a dedicated over-voltage protector, not a full-featured battery management IC. It does not include over-current, short-circuit, or under-voltage detection. For designs requiring comprehensive protection (e.g., over-current, temperature monitoring), a companion primary protector or fuel gauge is needed. The over-voltage threshold is factory-programmed; the part is not adjustable in-system, so verify the threshold version matches your cell chemistry (the BQ294502DRVR is one of several fixed-threshold variants in the family). ## Package and thermal considerations for layout The 6-WSON (2x2 mm) exposed pad requires a thermal via pattern under the pad for adequate heat sinking, especially if the pack sees sustained high ambient temperatures up to 110°C. ## Lifecycle and sourcing reality It is ROHS3 compliant. There is no official pin-compatible second source from another manufacturer, but the TI BQ2945xx family shares the same footprint with different threshold options — verify the threshold code before substituting.","metaTitle":"TI BQ294502DRVR Battery Protection IC, 2-3 Cell Li-Ion","metaDescription":"Texas Instruments BQ294502DRVR battery protection IC for 2-3 series Li-Ion cells with over-voltage fault protection.
