VNLD5090-E

VNLD5090-E Description

The VNLD5090-E from STMicroelectronics is a dual-channel low-side power switch designed for general-purpose load driving applications. Part of the OMNIFET III™ and VIPower™ series, this obsolete device integrates two N-channel MOSFETs with a 1:1 input-to-output ratio, capable of handling up to 13A per channel and 36V maximum load voltage. Its surface-mount 8SO package ensures compact PCB integration, while its 90mΩ (max) Rds(on) minimizes conduction losses, enhancing efficiency. The device operates without an external supply voltage, simplifying system design.

VNLD5090-E Features

• Robust Protection: Includes fixed current limiting, open-load detection, over-temperature, over-voltage, and UVLO safeguards, ensuring reliable operation under fault conditions.
• Auto-Restart & Status Flag: Automatically recovers from faults and provides diagnostic feedback, reducing downtime and simplifying troubleshooting.
• High Efficiency: Low Rds(on) (90mΩ max) reduces power dissipation, making it ideal for high-current applications.
• No Vcc/Vdd Required: Eliminates the need for an external supply, reducing BOM complexity.
• RoHS3 & REACH Compliant: Meets environmental standards, suitable for eco-conscious designs.

VNLD5090-E Applications

• Automotive Systems: Ideal for LED lighting control, relay driving, and power distribution in vehicles due to its high-voltage tolerance and fault protection.
• Industrial Load Switching: Suitable for solenoids, actuators, and motor control where robust protection and high current handling are critical.
• Consumer Electronics: Used in appliances and power management modules requiring compact, efficient switching solutions.

Conclusion of VNLD5090-E

The VNLD5090-E excels in high-current, low-side switching applications, offering integrated protection, high efficiency, and simplified design. While obsolete, its VIPower™ technology and dual-channel configuraion make it a legacy solution for demanding automotive, industrial, and consumer systems. Engineers seeking reliable load drivers with diagnostic features may still leverage its capabilities in existing designs or seek modern equivalents within STMicroelectronics' portfolio.
