Overview
Description
TPS22922YZPR is a Texas Instruments single-channel, high-side load switch that connects or disconnects a power rail to a load under EN control. It protects power rails in battery-powered devices and helps manage power sequences.
Key features:
- Low on-resistance and low quiescent current
- Integrated current limit and overcurrent protection
- Undervoltage lockout and thermal shutdown
- Reverse-current blocking
- EN pin for on/off control
Package: YZPR indicates TI’s RoHS-compliant, tape-and-reel version in a compact package.
Typical uses: microcontrollers, sensors, wearables, IoT devices, portable electronics.
How to use: connect IN to the source, OUT to the load, GND to ground, and drive EN to enable or disable power. Benefits: reduces inrush, protects against faults, and aids energy conservation by powering down unused rails. For exact electrical specs, consult the datasheet.

Pinout
- Pin count: 8 pins (8-pin package, e.g., MSOP-8/SON-8)
- Function: Single-channel high-side load switch with enable control and current-limit. VIN enters the device and is switched to VOUT to feed a load when EN is asserted. Includes protection features (overcurrent/short-circuit, UVLO). Pins typically include VIN, VOUT, GND, EN, ILIM/FB; remaining pins are NC.
