Power Distribution Switches, Load Drivers

VN920SP Description

The VN920SP from STMicroelectronics is a high-side power switch designed for general-purpose load driving applications. Part of the VIPower™ series, this obsolete surface-mount IC integrates a single N-channel MOSFET with a 1:1 input-to-output ratio, capable of handling up to 30A continuous current with a low Rds(on) of 15mΩ (max). It operates across a wide load voltage range of 5.5V to 36V, making it suitable for automotive, industrial, and power management systems. The device requires no external supply voltage (Vcc/Vdd), simplifying design integration. Packaged in a PWRSO10 tube, it complies with ROHS3 and REACH environmental standards.

VN920SP Features

• High-Side Configuration: Enables efficient load switching without ground reference issues.
• Robust Protection: Includes fixed current limiting, over-temperature shutdown, and over-voltage protection for enhanced reliability.
• Auto-Restart Function: Automatically recovers from fault conditions, reducing system downtime.
• Low Power Dissipation: Optimized 15mΩ Rds(on) minimizes heat generation at high currents.
• On/Off Interface: Simple control via a logic-level signal, eliminating complex drive circuitry.
• Wide Operating Range: Supports 5.5V–36V load voltages, ideal for 12V/24V automotive and industrial systems.

VN920SP Applications

• Automotive Systems: ECU power distribution, lighting controls, and solenoid drivers.
• Industrial Automation: Motor drives, relay replacements, and actuator control.
• Power Management: Hot-swap circuits, battery protection, and load switches in DC-DC converters.
• Consumer Electronics: High-current LED drivers and smart home device power stages.

Conclusion of VN920SP

The VN920SP excels in high-current switching with its low Rds(on), integrated protections, and auto-recovery features, offering a reliable solution for demanding environments. While marked obsolete, its VIPower™ architecture and wide voltage range make it a legacy choice for designs requiring rugged performance. Engineers should evaluate alternative modern equivalents from STMicroelectronics for new projects while considering this IC for maintenance or legacy system upgrades.
