TPS2556-Q1 Datasheet PDF – Power-Distribution Switch

Part Number: TPS2556-Q1

Function: Precision Automotive Adjustable Current-Limited Power-Distribution Switch

Package: S-PVSON 8 Pin Type

Manufacturer: Texas Instruments


TPS2556-Q1 datasheet



The TPS2556-Q1 and TPS2557-Q1 power-distribution switches are specialized for automotive applications which require precision current limiting or capacity to handle heavy capacitive loads and short circuits.

These devices offer a programmable current-limit threshold between 500 mA and 5 A (typical) via an external resistor. Control of the power-switch rise and fall times minimizes current surges during turnon or turnoff.


1. Meets USB current-limiting requirements

2. Adjustable current limit, 500 mA – 5 A (typ.)

3. ±6.5% current-limit accuracy at 4.5 A

4. Fast short-circuit response – 3.5 μs (typ.)

5. 22-mΩ high-side MOSFET

6. Operating range: 2.5 V to 6.5 V
