Power Distribution Switches, Load Drivers

VNQ810M Description

The VNQ810M from STMicroelectronics is a high-side power driver IC designed for general-purpose switching applications. This obsolete but robust device integrates four N-channel MOSFETs in a 1:1 input-to-output ratio, capable of handling load voltages from 5.5V to 36V with a maximum output current of 700mA per channel. Its surface-mount 28SO package ensures compact PCB integration, while the 150mOhm (max) Rds(on) minimizes conduction losses. The IC operates without an external Vcc/Vdd supply, simplifying system design.

VNQ810M Features

• High-Side Configuration: Enables direct control of loads connected to the positive rail.
• Advanced Protection: Includes fixed current limiting, open-load detection, over-temperature, and over-voltage protection for enhanced reliability.
• Auto-Restart & Status Flag: Automatically recovers from faults and provides diagnostic feedback.
• Low Power Dissipation: Optimized Rds(on) reduces heat generation.
• RoHS3 & REACH Compliant: Meets environmental and safety standards.
• On/Off Interface: Simplifies control logic integration.

VNQ810M Applications

Ideal for automotive, industrial, and consumer electronics, the VNQ810M excels in:

• Solenoid/Relay Driving: Robust protection ensures longevity in inductive load switching.
• LED Lighting Systems: Precise current control for high-power LED arrays.
• DC Motor Control: Safe operation in H-bridge or direct drive configurations.
• Power Distribution Modules: Efficiently manages multiple loads in battery-powered systems.

Conclusion of VNQ810M

While marked obsolete, the VNQ810M remains a highly reliable solution for medium-current switching with integrated protections and diagnostics. Its auto-restart capability and low Rds(on) make it suitable for harsh environments, though designers should consider modern alternatives for new projects. Legacy systems benefit from its durability and ease of integration.
