VNS1NV04D-E

VNS1NV04D-E Description

The VNS1NV04D-E from STMicroelectronics is a dual-channel low-side power switch designed for general-purpose load driving applications. Part of the OMNIFET II™ and VIPower™ series, this N-channel MOSFET-based driver integrates robust protection features while delivering 1.7A maximum output current per channel with a low Rds(on) of 250mΩ (max). It operates without an external supply voltage, simplifying design integration. The device is housed in an 8-pin SO package and is surface-mountable, making it suitable for compact PCB layouts. Though marked as obsolete, it remains relevant for legacy systems due to its reliability and compliance with ROHS3 and REACH environmental standards.

VNS1NV04D-E Features

• Dual Low-Side Outputs: Independent control of two channels with 1:1 input-to-output ratio for flexible load management.
• High Voltage Tolerance: Supports load voltages up to 36V, ideal for automotive and industrial environments.
• Integrated Protections: Includes fixed current limiting, over-temperature shutdown, and over-voltage clamping for enhanced system durability.
• Efficient Switching: Low Rds(on) minimizes power dissipation, improving thermal performance.
• No External Supply Needed: Eliminates the need for a separate Vcc/Vdd, reducing BOM complexity.
• Industry Compliance: Meets ROHS3, REACH, and ECCN EAR99 requirements for global deployment.

VNS1NV04D-E Applications

• Automotive Systems: ECU load driving, lighting control, and solenoid actuation due to high voltage tolerance.
• Industrial Automation: Relay/valve drivers, motor control modules, and power distribution in PLCs.
• Consumer Electronics: Low-side switching for displays, heaters, or peripheral devices.
• Legacy Equipment Maintenance: Replacing obsolete components in existing designs without redesigns.

Conclusion of VNS1NV04D-E

The VNS1NV04D-E excels in rugged, low-side switching applications with its dual-channel design, high-voltage capability, and built-in protections. While obsolete, its efficiency, ease of integration, and compliance make it a pragmatic choice for sustaining legacy systems or cost-sensitive designs. Engineers valuing reliability and simplicity will find it a compelling solution for automotive, industrial, and consumer load-driving needs.
