概要

Description

TPS22922YZPR is a Texas Instruments high‑side load switch used to power a load from a supply with controlled on/off. It integrates a switch FET, current‑limit, reverse‑current blocking, and over‑current/thermal protection. The EN pin gates turn‑on/off the output; the device supports soft‑start to limit inrush. It operates on a low‑voltage domain (roughly 1.65–5.5 V) with low quiescent current, making it suitable for battery‑powered and portable electronics. The YZPR suffix indicates a specific TI packaging option.
Typical applications include power rails for microcontrollers, sensors, and peripherals, where you need simple power gating and protection.
For exact electrical specs, pinout, current‑limit options, and packaging details, consult the TPS22922 datasheet on TI’s website.

Features

TPS22922YZPR features (concise):
- High-side load switch with enable (EN) control
- Wide input voltage range with reverse-current blocking
- Inrush current limiting via soft-start
- Overcurrent/short-circuit protection
- Thermal shutdown protection
- Undervoltage lockout (UVLO)
- Fault/Status indication pin (flag)
- Low quiescent current in standby
- Small 8-pin WSON (YZPR) package suitable for compact boards

Package

8-pin WSON package (2.0 x 2.0 mm).

Pinout

- Pin count: 8 pins (8-pin package, e.g., VSSOP-8/SOIC-8)
- Function: Dual high-side load switch with a common enable. It provides two protected power switches (IN to OUT1 and IN to OUT2) with current limiting and reverse-current protection, for turning two loads on/off from a single supply.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits.

Application

TPS22922YZPR is a high-side, current-limited load switch with reverse-current protection and soft-start. It gates power to a subsystem/rail, enabling hot‑swap sequencing and safe power-down while preventing backfeeding. Typical applications: battery-powered portable devices and wearables; IoT sensors; smartphones/tablets and other consumer electronics; USB peripherals and power hubs; automotive and industrial control systems needing reliable rail switching with current limiting.

Equivalent

TPS22922YZPR is TI’s 2-A, high-side load switch with enable (6-pin). There isn’t a single exact cross-reference. Closest TI alternatives in the same family: TPS22921, TPS22923, TPS22928 (different input ranges/current limits). External vendors also offer 2-A high-side load switches with EN and V_in up to ~5.5 V (e.g., Rohm/On Semiconductor/ST equivalents). For a precise substitute, use a cross-reference tool and compare specs: V_in 1.65–5.5 V, I_out ≈ 2 A, EN control, package.
