概述
Description
TPS2390DGKR is a Texas Instruments fault-protected high-side power switch (TPS2390 family). It provides protection for DC power rails by integrating current limiting, overcurrent/short-circuit protection, undervoltage/overvoltage detection, and thermal shutdown, with an enable control to turn the output on/off. It’s intended for hot‑swap protection, load switching, and rail protection in telecom, data-center, automotive, and consumer electronics applications. The DGKR suffix denotes a specific TI packaging/reel variant for the device. For exact electrical specs (current limit, voltage range, package type, and pinout), consult the TPS2390 datasheet and TI product folder.
Equivalent
There isn’t a direct one-for-one equivalent of TPS2390DGKR from another vendor. The closest equivalents are TI’s own TPS2390 family members with similar protection behavior, such as TPS2391 and TPS2392 (different current-limit/delay options). For cross-vendor substitutes, use TI’s Cross Reference tool or search for automotive hot‑swap/current‑limit high‑side switches with similar voltage/current specs from other vendors (e.g., On Semiconductor, Analog Devices).
