概述

Description

TPS22995RZFR is TI’s single-channel high-side load switch. It gates a power rail to a downstream load under an EN control, providing simple, protected power switching for battery-powered and portable systems. Key features include:
- Integrated FET with low on-resistance
- Current-limit protection
- Reverse-current blocking when the switch is off
- Undervoltage lockout and thermal shutdown
It’s designed for low quiescent current and straightforward power sequencing, suitable for powering sensors, MCUs, radios, and other peripherals in compact devices. The RZFR suffix indicates a specific TI packaging/ordering option. For exact electrical specs (on-resistance, current limit, EN polarity, pinout) and package details, consult the TPS22995 datasheet and TI product page.

Features

TPS22995RZFR features (highlights):
- Single-channel high-side load switch with current limit and protection
- Enable (EN) control to turn the switch on/off
- Reverse-current protection (blocks backflow when off)
- Overcurrent/short-circuit protection
- Undervoltage lockout (UVLO) for reliable startup
- Overtemperature protection
- Output discharge when disabled to remove residual voltage
- Low quiescent current and fast turn-on for power sequencing
- Small 8-pin package (RZFR) suitable for compact designs; RoHS-compliant and available in tape-and-reel
Note: For exact electrical specs (voltage range, current limit, rise/fall times), refer to the TI datasheet.

Package

8-pin VSON (3.0 x 3.0 mm) package, RoHS lead-free, available in tape-and-reel.

Pinout

- Pin count: 8 pins (RZ package)
- Function: Single-channel high-side load switch with enable control and current-limit protection. VIN is connected to VOUT when ENABLE is asserted, powering the downstream load with protection features (short-circuit/current limit). The FR suffix indicates a RoHS lead-free package.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- Company type: American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits.

Application

Applications of TPS22995RZFR:
- High-side power distribution and rail gating for MCUs/SoCs
- Battery-powered devices to isolate loads and prevent reverse current
- Automotive electronics needing protected, soft-start load switching
- Sensor, actuator, camera, and IoT subsystems with current limiting and fault protection
- Systems requiring inrush control and safe shutdown of supplies

Equivalent

TPS22995RZFR is TI’s high-side load switch. Equivalents depend on exact specs. Please provide VI range, IO max/current limit, enable behavior, soft-start, and preferred package. With that, I can give direct cross-references from ON Semiconductor, ST, Analog Devices, etc., or TI variants in other housings.
