概要
Description
The TPS22924DYZPR is a Texas Instruments single-channel high-side load switch used to power a downstream load from a main supply, with built-in protection and easy enable control. It gates power to peripherals or subcircuits in battery-powered or portable designs, enabling controlled turn-on/off, power sequencing, and fault protection.
Key features (typical):
- Enable control (on/off)
- Integrated protection: overcurrent/short-circuit protection, thermal shutdown, and reverse-current protection
- Undervoltage lockout and low quiescent current
- Suitable for low-voltage, battery-powered applications
Package/variant:
- DYZPR indicates the specific TI package and tape-and-reel shipping option (DYZ package).
Usage basics:
- Connect VIN to the supply, VOUT to the load, and drive EN with a logic signal.
- When enabled, the switch conducts with current limiting and protection; when disabled, it isolates the load.
For exact electrical specs, pinout, and package details, consult the latest TPS22924 datasheet and TI product page.

Features
Here are the key features of the TPS22924DYZPR:
- High-side load switch with enable (EN) control
- Wide input voltage range suitable for 1.65–5.5 V systems
- Integrated protection: overcurrent/short-circuit, undervoltage lockout, and thermal shutdown
- Reverse-current protection to prevent back-driving the source
- Auto-discharge of the output when the switch is disabled to prevent leakage/back-power
- Low quiescent current for battery-powered applications
- Low on-state resistance for minimal voltage drop
- Fast turn-on/turn-off performance
- Lead-free, tape-and-reel packaging option (DYZPR) suitable for automated assembly
