It integrates over-current, over-temperature, and over/under-voltage fault protection into a single 8-WSON package, eliminating the need for discrete comparators and reference circuits on the battery management board. Over-current protection monitors the discharge current and trips before the cell sees a short-circuit event. Over-temperature shuts down the pass element when the die temperature exceeds the safe limit — this is the primary safeguard against runaway charging in a hot environment. Over/under-voltage protection keeps the cell within its safe voltage window, preventing over-discharge damage and over-charge venting. Because all three protection functions are on-chip, the BOM for a basic Li-ion protection circuit reduces to the BQ24314ADSGRG4, a few external resistors and capacitors, and the MOSFET pass element. No separate voltage supervisor, no thermistor comparator, no current-sense amplifier. ## Package and thermal pad layout The 8-WFDFN exposed pad (supplier device package 8-WSON, 2x2 mm) requires a thermal via under the pad to the ground plane for heat sinking. Surface-mount assembly on standard FR-4 with a 0.5 mm pitch no-clean solder paste profile works. The small 2x2 mm footprint fits tight battery-pack PCBs where board area is at a premium. ## Sourcing and lifecycle posture The base product number is BQ24314, which covers multiple package and tape options. No official second-source or pin-compatible alternate is listed in the TI portfolio.","metaTitle":"BQ24314ADSGRG4 Li-ion Battery Protection IC, 8-WSON","metaDescription":"TI BQ24314ADSGRG4 battery protection IC for Li-ion packs.
