Product details

85 mOhm pass FET with adjustable current limit

The switch is controlled by an On/Off input and includes a status flag output to signal fault conditions.

Fault protection envelope

Three protection mechanisms are built in: adjustable current limiting, over-temperature shutdown, and under-voltage lockout (UVLO). The current limit is set with an external resistor, letting you tailor the trip point to the load's inrush and fault tolerance. The slew-rate controlled turn-on reduces inrush current and voltage droop on the upstream rail, which matters when the switch powers a capacitive load like a USB port or a sensor module.

Frequently asked questions

Does TPS2553DBVT have a status flag output?

Yes, the TPS2553DBVT includes a status flag output that asserts low when a fault condition — over-current or over-temperature — is detected.

What is the TPS2553DBVT used for?

It is a general-purpose high-side power switch used for USB port power, sensor supply switching, and general load distribution in systems running on 2.5 V to 6.5 V rails. The adjustable current limit and status flag make it a fit for applications that need controlled inrush and fault reporting.

Is TPS2553DBVT compatible with 3.3 V logic?

Yes, the On/Off input is non-inverting and the load voltage range includes 3.3 V. The enable threshold is compatible with 3.3 V logic levels, so a GPIO from a 3.3 V microcontroller can drive it directly.
