TPS2550 Datasheet Adjustable Current-limited Power-distribution Switches

Manufacturer: Texas Instruments

Overview: TPS2550, TPS2551 SLVS736C – FEBRUARY 2008 – REVISED OCTOBER 2023 TPS255x Adjustable Current-Limited Power-Distribution Switches.

General Description

The TPS2550/51 power-distribution switch is intended for applications where heavy capacitive loads and short-circuits are likely to be encountered, incorporating a 100-mΩ, N-channel MOSFET in a single package.

The current-limit threshold is user adjustable between 100 mA and 1.1 A via an external resistor.

The power-switch rise and fall times are controlled to minimize current surges during switching.
