概述

Description

VNQ5050AK-E is STMicroelectronics’ single-channel high-side switch with an integrated MOSFET, designed for automotive/industrial loads. It lets a microcontroller turn a load on/off from the battery rail without an external driver.
Key features
- 6–28 V operating range (suits 12/24 V automotive systems) with protection against supply transients
- Built-in 5 A current limit and short-circuit protection
- Thermal shutdown and undervoltage lockout
- Reverse-polarity and load-dump resilience
- Diagnostic output (DIAG) to indicate faults or load current status
- PWM-friendly input for switching control; no external driver required
- Automotive-grade (AEC-Q100) with extended temperature range in an 8-pin package
Typical usage
- IN from MCU, OUT to the load, VBAT to supply, GND to ground; monitor DIAG with a microcontroller
- Suitable for lighting, pumps, solenoids, fans, and other switched automotive/industrial loads
Note: Check the latest datasheet for exact electrical specs, pinout, and package details.

Features

VNQ5050AK-E is a one-channel high-side load switch for automotive 60V systems. Key features:
- 1-channel high-side switch with integrated current limit (about 0.5 A) and protection
- Overcurrent/short-circuit protection with automatic retry
- Thermal shutdown protection
- Undervoltage lockout (UVLO) on input
- Enable input for on/off control; PWM-friendly
- Reverse battery and reverse-current protection
- Diagnostic/status output to indicate ON, OFF, or fault
- Low quiescent current in OFF state
- Automotive-grade (AEC-Q100) and RoHS compliant
- Available in small packages (e.g., 8-pin SO/HVSON variants)
Note: exact current limit and package options can vary by revision; consult the datasheet for precise specs.

Package

An 8-pin package: SO-8 (SOP-8) leaded package.

Pinout

- Pin count: 8 pins (SO-8/SOP-8 package).
- Function: Automotive high-side switch with ~5 A current rating. It controls power from the supply to the load via OUT under control of IN/EN, with built-in protections (undervoltage, overcurrent/short to ground, overtemperature, reverse battery) and diagnostic/current-sense feedback (DIAG/IS).

Manufacturer

- Manufacturer: Vishay Intertechnology, Inc. (Vishay)
- What kind of company: A global, U.S.-based semiconductor and passive electronic components manufacturer that designs and makes discrete semiconductors, resistors, capacitors, inductors, and related components.

Application

- Automotive 12/24 V loads (lighting, relays, motors, pumps)
- Microcontroller-controlled high-side switches in automotive and industrial systems
- Battery-powered devices requiring protection (reverse polarity, short-circuit, thermal shutdown)

Equivalent

Equivalent devices (5 A automotive high-side switches with current limit and protections) include:
- Infineon TLE9250QX / TLE9255QX
- Texas Instruments TPS1H100-Q1 (and TPS1H130-Q1)
- ROHM BD9S series (e.g., BD9S301/BD9S302)
