Product details

Fault protection set

Built-in fault protection includes adjustable current limiting, over-temperature shutdown, and undervoltage lockout (UVLO). The current limit is set with an external resistor, letting you tailor the trip point below the 1.1 A max.

Slew-rate control and On/Off interface

The switch features slew-rate controlled turn-on to limit inrush current into capacitive loads. The On/Off interface is non-inverting — a logic high on the enable pin turns the output on.

Frequently asked questions

What are the faults protected by TPS2550DBVRG4?

It protects against adjustable current limiting, over-temperature, and undervoltage lockout (UVLO).

What is the on-resistance of TPS2550DBVRG4?

Typical on-resistance is 85 mOhm.

Can TPS2550DBVRG4 be used for USB power distribution?

Yes. The 1.1 A max output, adjustable current limit, and slew-rate control make it suitable for USB port power switching on 5 V rails, where inrush limiting and overcurrent protection are needed.
