Power Distribution Switches, Load Drivers

VN5012AK-E Description

The VN5012AK-E from STMicroelectronics is a high-side N-channel power switch designed for general-purpose load driving applications. Part of the VIPower™ series, this obsolete but robust IC integrates a 45A output current capability with a low Rds(on) of 12mΩ (max), ensuring efficient power handling with minimal conduction losses. It operates across a 4.5V to 36V load voltage range and features a 1:1 input-to-output ratio, simplifying control logic. The device is housed in a PowerSSO-24 surface-mount package, making it suitable for compact PCB designs.

VN5012AK-E Features

• High-Side Configuration: Ideal for direct load switching without additional circuitry.
• Advanced Protection: Includes fixed current limiting, over-temperature, and over-voltage fault protection, enhancing system reliability.
• Auto Restart Function: Automatically recovers from fault conditions, reducing downtime.
• Low Power Dissipation: 12mΩ Rds(on) minimizes heat generation under high-current loads.
• Compliance: ROHS3 and REACH compliant, meeting environmental standards.
• Wide Voltage Range: Supports 4.5V–36V loads, suitable for automotive and industrial applications.

VN5012AK-E Applications

• Automotive Systems: ECU power distribution, LED lighting drivers, and solenoid control.
• Industrial Automation: Motor drives, actuator control, and high-current switching modules.
• Power Management: Hot-swap circuits, load switches, and battery protection systems.
• Consumer Electronics: High-power LED arrays and appliance control.

Conclusion of VN5012AK-E

The VN5012AK-E excels in high-current switching with its low Rds(on), integrated protections, and auto-restart capability, making it a reliable choice for demanding environments. While obsolete, its performance in automotive and industrial applications remains noteworthy. Engineers seeking alternatives should consider newer VIPower™ variants, but this model’s rugged design and efficiency ensure continued relevance in legacy systems.
