概述

Description

TPS2390DGKR is a Texas Instruments high-side protection switch with built-in current limit and fault protection. It protects a downstream load from short circuits and overcurrent, and also includes undervoltage lockout and thermal shutdown. When a fault is detected, it limits or disconnects current and can signal the fault to a controller. This lets you implement power-rail protection with minimal external components, suitable for automotive, industrial, and portable applications. The DGKR suffix indicates TI’s packaging options (D-series RoHS-compliant, tape-and-reel reel packaging). For exact electrical specs (voltage range, current limit, timing, and pinout), consult the TPS2390DGKR datasheet.

Features

Here are the key features of TPS2390DGKR (concise):
- High-side load switch with current-limiting protection
- Reverse-polarity protection
- Overcurrent/short-circuit protection (hiccup/auto-retry behavior)
- Undervoltage and overvoltage lockout
- Thermal shutdown protection
- Enable input to turn the switch on/off; soft-start to limit inrush
- Small 8-pin DGK package
- Suitable for portable/automotive power rails with low quiescent current
Note: For exact electrical specs (voltage range, current limit, timing, etc.), please consult the datasheet.

Package

8-pin VSSOP (3.0 × 3.0 mm) package.

Pinout

- Pin count: 8 pins (8-pin package).
- Function: TI TPS2390DGKR is a high-side hot-swap/current-limiting protection device that drives an external MOSFET to limit inrush and protect the supply from overcurrent/short conditions; includes fault/status signaling.

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits and other related semiconductor products.

Application

TPS2390DGKR is a protection switch for DC power paths. Typical applications include:
- Hot-swap protection for power rails/backplanes
- Overcurrent/short-circuit protection with current limiting
- Fault indication for system monitoring
- Power-path switching in telecom, networking, servers, and storage equipment
- General consumer/industrial/automotive electronics requiring safe power distribution
