概要
Description
TPS22968QDMGRQ1 is TI’s automotive-grade, single-channel high-side load switch. It sits between the supply and a downstream load to protect and power automotive/subsystem circuits with minimal BOM.
Key features:
- Integrated power MOSFET with current-limit/short-circuit protection
- Reverse-current protection and undervoltage lockout
- Thermal shutdown for safe operation
- Enable pin to turn the switch on/off
- Q1 suffix = AEC-Q100 Grade 1 automotive qualification
- DMG package (small surface-mount, RoHS compliant)
Typical uses include powering microcontrollers, sensors, and other loads in vehicles or harsh environments, where protection from transients and overcurrent is required. For exact specs (input voltage range, current limit, quiescent current, and package details), consult the TI TPS22968 datasheet.

Pinout
Pin count: 8 pins (QFN package, TPS22968QDMGRQ1).
Function: A single-channel high-side power-load switch with current-limit and protection. VIN feeds the switch, VOUT supplies the load, EN enables/disables the switch, ILIM sets the current limit (via a resistor), and GND is the reference. Includes overcurrent/short-circuit protection and thermal shutdown.
