Power Distribution Switches, Load Drivers

VNQ860SP Description

The VNQ860SP from STMicroelectronics is a high-side power switch belonging to the VIPower™ series, designed for general-purpose load driving applications. This 4-channel N-channel MOSFET-based driver operates with a 5.5V to 36V load voltage range, making it suitable for automotive, industrial, and consumer electronics. The device integrates four independent high-side switches, each capable of delivering up to 250mA continuous current with a low Rds(on) of 270mΩ (max), ensuring efficient power management.

VNQ860SP Features

• High-Side Configuration: Simplifies circuit design by eliminating the need for external supply (Vcc/Vdd).
• Robust Protection: Includes current limiting, over-temperature, and over-voltage protection, enhancing system reliability.
• Auto-Restart & Status Flag: Automatically recovers from faults and provides diagnostic feedback.
• Low Power Loss: Optimized Rds(on) minimizes conduction losses.
• Surface-Mount (PWRSO10): Compact packaging suitable for space-constrained applications.
• RoHS3 & REACH Compliant: Meets environmental and regulatory standards.

VNQ860SP Applications

• Automotive Systems: ECU loads, lighting controls, and motor drivers.
• Industrial Automation: Solenoid/relay driving and PLC I/O modules.
• Consumer Electronics: Power distribution in smart home devices.
• Diagnostic & Protection-Critical Systems: Where fault monitoring (via status flag) is essential.

Conclusion of VNQ860SP

The VNQ860SP excels in multi-channel high-side switching with integrated protection and diagnostics, reducing external component count. Its wide voltage range and low Rds(on) make it ideal for high-efficiency, fault-tolerant designs. While obsolete, its VIPower™ architecture remains a benchmark for reliability in demanding environments. Engineers should consider alternative STMicroelectronics models for new designs while leveraging existing stock for legacy systems.
