Power Distribution Switches, Load Drivers

VN02H Description

The VN02H from STMicroelectronics is a high-side N-channel power switch designed for general-purpose load driving applications. This obsolete device features a 1:1 input-to-output ratio, supporting load voltages from 5V to 36V with a maximum output current of 6A. It integrates a low Rds(on) of 400mOhm (max), ensuring efficient power delivery with minimal conduction losses. The through-hole (PENTAWATT package) design facilitates robust mechanical integration in industrial and automotive systems.

VN02H Features

• High-Side Configuration: Simplifies circuit design by eliminating the need for an external supply (Vcc/Vdd not required).
• Integrated Protections: Includes open-load detection and over-temperature fault protection, enhancing system reliability.
• Status Flag: Provides diagnostic feedback for fault conditions, improving maintenance and troubleshooting.
• RoHS3 & REACH Compliant: Meets environmental and regulatory standards for global deployment.
• Low Power Dissipation: Optimized Rds(on) reduces heat generation, suitable for high-duty-cycle applications.
• On/Off Interface: Simple control via a logic-level input, enabling easy integration into digital systems.

VN02H Applications

• Automotive Systems: Ideal for driving resistive or inductive loads (e.g., solenoids, lamps) in 12V/24V vehicle networks.
• Industrial Controls: Relays, actuators, and motor drivers in factory automation equipment.
• Power Distribution: Solid-state replacement for electromechanical relays in DC power management.
• Diagnostic Tools: Fault-protection features make it suitable for test and measurement devices requiring load monitoring.

Conclusion of VN02H

The VN02H excels in rugged, high-current switching with its low Rds(on), integrated protections, and diagnostic capabilities. While now obsolete, its 5V–36V range and 6A output remain valuable for legacy designs in automotive and industrial sectors. Engineers seeking alternatives should consider STMicroelectronics' newer ROHS3-compliant successors with similar performance profiles.
