Description
TPS22968NQDMGRQ1 is TI’s protected high-side load switch. It provides a single-channel MOSFET to power a load from a supply (e.g., a battery) with built-in protection and simple control. Features include current-limit/short-circuit protection, undervoltage lockout, thermal shutdown, reverse-current blocking, and an enable (EN) input to turn the switch on or off. It helps protect rails and manage inrush without external FETs or discrete protection circuitry.
Key features:
- Single-channel high-side switch with EN control
- Overcurrent/short-circuit protection (auto-retry)
- Undervoltage lockout and thermal shutdown
- Reverse-current blocking
- Soft-start to limiter inrush
- Low Rds(on) in a compact package
- Input range roughly 0.8–5.5 V (verify datasheet)
- Available in small packages (NQDMGRQ1 variant)
Typical applications: battery-powered devices, power rails for MCUs/sensors, cameras, displays, and other peripherals.
For exact electrical specs, pinout, and packaging, consult the TPS22968NQDMGRQ1 datasheet/product page.

Equivalent
TPS22968NQDMGRQ1 is an automotive-grade, 1.5 A high-side load switch with EN control and reverse-current blocking. There isn't an exact cross-vendor equivalent. Closest alternatives from other vendors are 1–2 A high-side load switches with EN and reverse-current protection (e.g., from On Semiconductor and STMicroelectronics). For an exact replacement, use distributor TI cross-reference tools.
