Overview
The TPS2590RSAT, produced by Texas Instruments, is a highly integrated hot-swap power management device designed to provide superior protection in systems where the load is powered by voltage busses up to 20 V. This device is particularly suited for applications requiring protection against load shorts and other faults that could interrupt or damage system components. The TPS2590 operates within a voltage range of 3 V to 20 V, making it compatible with standard bus voltages as low as 3.3 V. It features an integrated pass MOSFET and multiple programmable protection features, including fault timers, fault current limits, and hard current limits. The device is packaged in a 16-pin QFN package and supports a junction temperature range of –40°C to 125°C.
