Key Features

  • Single-channel intelligent load switch with integrated thermal shutdown at 130°C for robust overcurrent and overtemperature protection
  • Compact 20-pin QFN EP (VQFN) package with exposed pad for excellent thermal dissipation in space-constrained power designs
  • RoHS and Pb-free compliant (JESD-609 e4) supporting 3.278 W power switching for reliable hot-swap and inrush management

Applications

The TPS2231RGPTG4 is designed for USB power management, hot-swap controllers, and single-rail power distribution in servers, networking equipment, and embedded systems. Its integrated thermal shutdown and load switch capability make it suitable for protecting sensitive loads from overcurrent conditions in industrial and communications hardware. The compact QFN footprint enables high-density PCB layouts in portable and space-constrained applications.

Frequently Asked Questions

What is the thermal shutdown temperature of the TPS2231RGPTG4?

The TPS2231RGPTG4 features an integrated thermal shutdown threshold of 130°C, which automatically disables the load switch when junction temperature exceeds this limit, protecting both the device and downstream circuitry from overtemperature damage.

How many channels does the TPS2231RGPTG4 have and what power can it switch?

The TPS2231RGPTG4 is a single-channel power interface switch capable of switching up to 3.278 W. Despite being listed as a 6-channel family part, this specific variant provides one channel of intelligent load switching with built-in protection features.

What package is the TPS2231RGPTG4 available in, and is it lead-free?

The TPS2231RGPTG4 is available in a 20-pin QFN EP (exposed pad) package, JESD-30 code S-PQCC-N20, with a 0.16-inch square body. It is fully Pb-free and RoHS compliant per JESD-609 code e4, suitable for lead-free reflow soldering.

What applications is the TPS2231RGPTG4 best suited for?

The TPS2231RGPTG4 is ideal for USB power switching, hot-plug management, and single-rail load protection in networking, server, and embedded computing platforms. Its thermal shutdown and compact QFN package make it well-suited for high-density board designs requiring reliable power distribution.
