Product details

High-side switch with adjustable current limit

It integrates an N-channel MOSFET with a typical on-resistance of 85 mOhm, a slew-rate-controlled output to limit inrush, and a status flag that asserts when the output is in current-limit or thermal-shutdown.

Load voltage and protection envelope

The switch operates with a load voltage from 2.5 V to 6.5 V and delivers up to 1.5 A continuous output. The fault protection set includes adjustable current limiting, over-temperature shutdown, and undervoltage lockout (UVLO), which together cover the main failure modes for a USB port or general-purpose power-rail switch.

Frequently asked questions

What is the typical Rds(on) for TPS2552DBVT-1?

The typical on-resistance is 85 mOhm, specified at the N-channel MOSFET output.

What is the difference between TPS2552 and TPS2553?

The TPS2552 and TPS2553 share the same package and basic feature set, but the TPS2553 includes an additional enable logic option. For the TPS2552DBVT-1, the input type is non-inverting with an On/Off interface.
