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.
