VN5160S-E

VN5160S-E Description

The VN5160S-E from STMicroelectronics is a high-side power switch designed for general-purpose load driving applications. Part of the VIPower™ series, this N-channel MOSFET-based driver integrates advanced protection features in a compact surface-mount 8SO package. It operates with a 4.5V to 36V load voltage range, delivering up to 3.8A output current with a low Rds(on) of 160mΩ (max), ensuring efficient power handling. The device requires no external supply voltage (Vcc/Vdd), simplifying system design. Though marked obsolete, it remains relevant for legacy systems due to its robust performance and compliance with ROHS3 and REACH environmental standards.

VN5160S-E Features

• High-Side Configuration: Enables direct control of loads connected to the positive rail.
• Integrated Protections: Includes fixed current limiting, open-load detection, over-temperature shutdown, and over-voltage protection, enhancing reliability.
• Auto-Restart Function: Automatically recovers from fault conditions, reducing downtime.
• 1:1 Input-to-Output Ratio: Simplifies interface logic with direct On/Off control.
• Wide Operating Range: Supports 4.5V–36V loads, ideal for automotive and industrial applications.
• Low Power Dissipation: Optimized Rds(on) minimizes heat generation.

VN5160S-E Applications

• Automotive Systems: ECU loads, lighting controls, and solenoid drivers.
• Industrial Automation: Relay/valve actuation and motor control in harsh environments.
• Power Distribution: Solid-state replacement for mechanical relays in PCB designs.
• Legacy Equipment Maintenance: Suitable for repairs or upgrades of older systems requiring high-side switching.

Conclusion of VN5160S-E

The VN5160S-E excels in high-current switching with its robust protection suite and minimal external component requirements. While obsolete, its VIPower™ technology and wide voltage range make it a pragmatic choice for durable, fault-tolerant designs. Engineers valuing simplicity, reliability, and compliance will find it particularly useful in automotive and industrial contexts, despite newer alternatives in the market.
