TPS2557DRBR Description

Short technical summary and product information.

The TPS2557DRBR from Texas Instruments is a high-side power distribution switch designed for applications demanding precise current limiting or handling heavy capacitive loads and short circuits. This N-channel MOSFET switch operates within a voltage range of 2.5V to 6.5V and offers an adjustable current limit typically between 500mA and 5A, controlled via an external resistor.

 

Key electrical characteristics include a low typical Rds On of 22mOhm, ensuring efficient power delivery. It features slew rate control to minimize current surges during turn-on and turn-off, and a fast overcurrent response time of 3.5µs typical. The device includes fault protection mechanisms such as adjustable current limiting, over-temperature protection, and undervoltage lockout (UVLO).

 

Packaged in an 8-SON (3x3) or 8-VDFN exposed pad, the TPS2557DRBR is designed for surface mounting. It operates across a wide temperature range of -40°C to 125°C. The switch has an active-high enable and provides a status flag output during overcurrent and overtemperature conditions. With a maximum standby supply current of 2µA, it is suitable for power-sensitive applications.
