TPS25944ARVCT Description

Short technical summary and product information.

The Texas Instruments TPS25944ARVCT is an active eFuse and hot-swap controller designed for power protection. It operates within a voltage range of 2.7V to 18V and offers an adjustable current limit from 0.6A to 5.2A, with a maximum continuous current of 5.3A.

 

Key electrical characteristics include a typical on-resistance of 42mΩ and adjustable soft-start functionality. The device provides essential protection features such as overcurrent protection, overvoltage protection, short-circuit protection, and thermal shutdown. It also includes a fault output and a power good signal. The eFuse incorporates reverse current blocking and a circuit breaker function with a 4ms response time.

 

Packaged in a 20-WQFN (3x4) surface-mount configuration, the TPS25944ARVCT operates across a temperature range of -40°C to 125°C. Its typical quiescent current is 199µA when operating and reduces to 15µA when disabled, contributing to power efficiency.
