Product details

1.1 A high-side switch with adjustable current limit

The TPS2551DRVT is a single-channel, high-side power-distribution switch from Texas Instruments, rated for a continuous output current of 1.1 A with a typical on-resistance of 100 mOhm. It integrates adjustable current limiting, over-temperature protection, and undervoltage lockout (UVLO), making it a self-contained load switch for USB ports, peripheral power rails, and general-purpose 2.5 V to 6.5 V distribution.

This means TI will continue to support existing production for a period, but the part is not intended for new-design wins.

Adjustable current limit — no external sense resistor

The current limit is adjustable via a single external resistor, which sets the threshold between the switch's internal current-sense amplifier and the 1.1 A maximum. The slew-rate controlled turn-on (listed as a feature) reduces inrush current on capacitive loads, which is useful when the switch powers a bank of decoupling capacitors at a USB port or a sensor module.

Frequently asked questions

What is the current limit of the TPS2551DRVT?

The maximum continuous output current is 1.1 A. The current limit is adjustable via an external resistor, so the actual threshold can be set lower than 1.1 A depending on the resistor value.

Can the TPS2551DRVT be used with a 5V supply?

Yes. The load voltage range is 2.5 V to 6.5 V, so 5 V is well within the operating window. The switch does not require a separate Vcc supply — it is self-powered from the load rail.
