Product Overview
TPS25982 is a Texas Instruments smart eFuse hot-swap protection IC for Power_Management designs. The device integrates an internal 2.7 mOhm typical power switch and supports a recommended input voltage range of 2.7 to 24 V, with an absolute maximum IN-pin range of -0.3 to 30 V.
Protection behavior is configurable by device option. The family supports active current limiter and circuit breaker overcurrent response versions, with OVLO options of 3.7 V, 7.6 V, 16.9 V, or no OVLO depending on the orderable part number. The adjustable current-limit threshold spans 2 to 15 A, with ±8% typical current-limit accuracy for ILIM above 5 A.
The RGE package is a 24-pin QFN with a 4.0 mm x 4.0 mm footprint. Thermal data for this package includes 34.6°C/W junction-to-ambient resistance and 1.6°C/W junction-to-case bottom resistance. Recommended operating conditions specify up to 15 A continuous switch current, -15 to 125°C junction temperature, and defined voltage limits for OUT, EN/UVLO, PG, and timing or control capacitors.
