Overview
The TPS2590RSAR, 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 busses up to 20 V. This device is particularly suited for applications requiring protection against load shorts and other fault conditions that could interrupt or damage system components. The TPS2590RSAR features a maximum UV turn-on threshold of 2.9 V, making it compatible with standard bus voltages as low as 3.3 V. It is housed in a 16-pin QFN package and operates over a junction temperature range of –40°C to 125°C.
