Power Distribution Switches, Load Drivers

VNQ660SP Description

The VNQ660SP from STMicroelectronics is a high-side power distribution switch designed for general-purpose load driving applications. This obsolete but robust IC integrates four N-channel MOSFETs in a 1:1 input-to-output ratio, capable of handling up to 6A per channel with a low Rds(on) of 40mΩ (typical). It operates over a wide load voltage range (6V to 36V), making it suitable for automotive, industrial, and power management systems. The device is packaged in a surface-mount PWRSO10 tube, ensuring compact integration.

VNQ660SP Features

• High-Side Configuration: Enables efficient load switching without requiring a separate supply voltage (Vcc/Vdd).
• Advanced Protection: Integrates current limiting (fixed), open-load detection, over-temperature, and over-voltage protection, enhancing system reliability.
• Status Flag: Provides real-time fault monitoring for diagnostics.
• Low Power Dissipation: Achieved through low Rds(on), reducing heat generation.
• RoHS3 & REACH Compliant: Meets environmental and regulatory standards.
• Robust Interface: Simple On/Off control for easy integration into digital systems.

VNQ660SP Applications

• Automotive Systems: Ideal for driving lamps, solenoids, or relays in 12V/24V automotive networks.
• Industrial Automation: Powers actuators, valves, and motor controls with high-current handling.
• Power Distribution Units (PDUs): Suitable for hot-swappable modules due to fault protection features.
• LED Drivers: Efficiently manages high-current LED arrays with open-load detection.

Conclusion of VNQ660SP

While marked as obsolete, the VNQ660SP remains a high-performance solution for high-side switching applications demanding low conduction losses and integrated protection. Its 4-channel design, wide voltage range, and diagnostic capabilities make it a versatile choice for legacy systems in automotive and industrial environments. Engineers seeking reliable load drivers with minimal external components may still find value in existing stock or alternative STMicroelectronics successors.
