Overview

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).

Pinout

- Pin count: 8 pins (VSSOP-8/SO-8 package).
- Function: High-side protection switch with current limiting and fault protection (short-circuit/overcurrent protection) for a load on a power rail (hot‑swap protection).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits; one of the world’s largest chipmakers.

Application

TPS2390DGKR is a high‑side current‑limiting switch with overcurrent/short‑circuit protection for DC power rails. Common applications include:
- Automotive and industrial power distribution
- USB/battery charger and power‑adapter input protection
- LED driver circuits requiring reliable current limit
- Telecommunication and data‑interface power rails
- Battery‑management and portable equipment protection
- General protection of sensitive circuits from short circuits and surges

Package

TPS2390DGKR comes in an 8‑pin VSSOP package (3.0 × 3.0 mm) with tape‑and‑reel packaging.
