VN750PT

VN750PT Description

The VN750PT from STMicroelectronics is a high-side power switch designed for general-purpose load driving applications. Part of the VIPower™ series, this obsolete N-channel MOSFET-based driver integrates advanced protection features in a compact PPAK (PowerPAK) surface-mount package. It supports a 5.5V to 36V load voltage range and delivers a maximum output current of 6A, with a low Rds(on) of 60mΩ (max) for efficient power handling. The device operates without an external Vcc/Vdd supply, simplifying system design.

VN750PT Features

• High-Side Configuration: Enables direct control of loads connected to the positive rail.
• Integrated Protections: Includes current limiting (fixed), open-load detection, over-temperature, and over-voltage shutdown for robust fault management.
• Auto-Restart & Status Flag: Automatically recovers from faults and provides diagnostic feedback.
• 1:1 Input-Output Ratio: Simplifies interface logic with direct On/Off control.
• PPAK Package: Optimized for thermal performance and space-constrained PCB layouts.
• REACH Unaffected & MSL 3: Compliant with environmental regulations and suitable for industrial environments.

VN750PT Applications

Ideal for automotive, industrial, and consumer electronics, the VN750PT excels in:

• Solenoid/Relay Driving: High-current switching with built-in protections.
• LED Lighting Systems: Efficient control of high-power LED arrays.
• DC Motor Management: Safe operation in actuators or small motor drives.
• Power Distribution Modules: Reliable load switching in 12V/24V systems.

Conclusion of VN750PT

While marked obsolete, the VN750PT remains a technically robust solution for high-side switching, combining low conduction losses, comprehensive protections, and a compact form factor. Its auto-recovery and diagnostic capabilities make it suitable for mission-critical systems requiring fail-safe operation. Engineers evaluating alternatives should consider its VIPower™ heritage for legacy designs or seek newer equivalents with similar specs.
