VND810SP

VND810SP Description

The VND810SP from STMicroelectronics is a high-side power switch designed for general-purpose load driving applications. Part of the VIPower™ series, this dual-channel device integrates N-channel MOSFETs with advanced protection features, delivering 3.5A maximum output current per channel. It operates over a wide load voltage range (5.5V to 36V) and features a low Rds(on) of 160mΩ (max), ensuring efficient power handling with minimal losses. The device is housed in a surface-mount PWRSO10 package and is RoHS3 compliant, though it is now marked as obsolete.

VND810SP Features

• High-Side Configuration: Simplifies design by eliminating the need for an external supply (Vcc/Vdd not required).
• Integrated Protections: Includes current limiting (fixed), open-load detection, over-temperature shutdown, and over-voltage protection, enhancing system reliability.
• Auto-Restart & Status Flag: Automatically recovers from faults and provides diagnostic feedback, reducing downtime.
• Low Power Dissipation: Optimized Rds(on) minimizes heat generation, suitable for compact designs.
• 1:1 Input-to-Output Ratio: Direct control logic simplifies interfacing with microcontrollers.

VND810SP Applications

• Automotive Systems: Ideal for driving lamps, solenoids, or relays in 12V/24V automotive networks due to robust fault tolerance.
• Industrial Controls: Used in PLC outputs, motor drivers, and actuator controls where high-side switching is preferred.
• Power Distribution: Suitable for hot-swap circuits or load management in telecom/power supplies.
• Consumer Electronics: Enables safe power switching in appliances with inductive/capacitive loads.

Conclusion of VND810SP

The VND810SP excels in high-reliability applications requiring compact, protected high-side switching. Its VIPower™ integration reduces external component count, while comprehensive fault coverage ensures robust operation in harsh environments. Though obsolete, its legacy designs benefit from features like auto-restart and low Rds(on), making it a historical benchmark for dual-channel power switches. Engineers should consider modern alternatives from STMicroelectronics for new designs.
