Product details

Active high-side switch with 2.5 A continuous rating

The TPS2554DRCR: The output is an N-channel MOSFET with an on/off control interface and a status flag output that asserts when the switch is in current-limit or thermal-shutdown.

73 mOhm Rds(on) — voltage drop and thermal budget

At 2.5 A the typical drop across the switch is 73 mOhm, dissipating power within the package rating.

Adjustable current limit and fault protection set

The current limit is set with an external resistor from the ILIM pin to ground, allowing the threshold to be trimmed below the maximum. The protection block includes.

The wide range also covers cold-start conditions down to -40°C without output degradation.

Frequently asked questions

What is the maximum output current for TPS2554DRCR?

The maximum continuous output current is 2.5 A. The current limit is adjustable via an external resistor, but the absolute maximum is 2.5 A.

What are the alternatives to TPS2554DRCR?

The base product number TPS2554 covers several package and tape options. The TPS2554DRCR is the 10-VSON (3x3) variant in Tape & Reel. Pin-compatible siblings in the same family include the TPS2554D (same die, different package) — confirm the package and tape orientation before substituting.
