概述

Description

TPS22968NQDMGRQ1 is Texas Instruments’ single-channel, high-side load switch with an enable (EN) control. It gates power to a downstream load, providing protection and efficient power management for battery-powered and portable devices. Key features include fixed current-limit protection (short-circuit/overcurrent), reverse-current blocking when off, undervoltage lockout, thermal shutdown, and automatic output discharge when disabled. The device uses a low on-resistance FET for minimal voltage drop and operates from a typical single-supply range (about 1.65–5.5 V, depending on variant). The NQDMGRQ1 suffix identifies the specific packaging (small QFN) and RoHS-compliant, tape-and-reel format. Typical applications: power-gating microcontrollers, sensors, memory, and other peripherals to reduce quiescent current and protect rails.

Features

TPS22968NQDMGRQ1 features (concise):
- 1-channel load switch with current limit and reverse-current protection
- Wide input-voltage range suitable for typical 1.65–5.5 V systems
- Enable (EN) input to turn the switch on/off
- Undervoltage lockout (UVLO) and overcurrent/short-circuit protection
- Thermal shutdown protection
- Soft-start to limit inrush
- 100% duty-cycle operation
- Low quiescent current
- Small 6-pin QFN package (3×3 mm) with RoHS/compliant options
Optional: for precise electrical specs, refer to the TI datasheet.

Package

TPS22968NQDMGRQ1 comes in an 8-pin QFN package (3×3 mm), also referred to as DQFN-8.

Pinout

Pin count: 8 pins.
Function: One-channel high-side load switch. VIN is connected to VOUT when EN is asserted; includes protection features (current limit, overcurrent/thermal protection, and reverse-battery protection) with GND as reference.

Manufacturer

Manufacturer: Texas Instruments Incorporated (TI).
What kind of company: TI is a multinational American semiconductor company that designs and manufactures analog and embedded processing integrated circuits, sensors, and other electronics components. It is one of the world’s largest semiconductor makers, headquartered in Dallas, Texas.

Application

TPS22968NQDMGRQ1 is a high-side load switch with current limit, reverse-current blocking, and thermal shutdown. Typical applications:
- Power gating/sequencing for MCUs, sensors, and peripherals
- Battery-powered devices (wearables, IoT, handhelds)
- Inrush control and hot‑swap protection for rails
- Reverse-current protection and short‑circuit protection for system rails
These features enable efficient, protected, small-footprint power-distribution in portable and embedded systems.
