VN808-E

VN808-E Description

The VN808-E from STMicroelectronics is a high-performance 8-channel high-side driver designed for general-purpose power switching applications. Part of the VIPower™ series, it integrates N-channel power MOSFETs with a 1:1 input-to-output ratio, enabling efficient load control. The device operates over a wide load voltage range (10.5V to 45V) and delivers a maximum output current of 700mA per channel, making it suitable for demanding industrial and automotive systems. Its surface-mount PWRSO36 package ensures compact integration, while RoHS3 compliance and REACH unaffected status align with environmental regulations.

VN808-E Features

• High-Side Configuration: Simplifies design by eliminating the need for external supply voltage (Vcc/Vdd).
• Advanced Protection: Includes fixed current limiting and over-temperature fault protection, with auto-restart functionality for robust operation.
• Low Rds(On): 150mΩ typical conduction resistance minimizes power losses.
• Status Flag: Provides real-time fault monitoring for enhanced system diagnostics.
• Wide Voltage Range: Supports 10.5V–45V loads, ideal for 12V/24V automotive and industrial systems.
• On/Off Interface: Simple control via logic-level inputs.

VN808-E Applications

The VN808-E excels in:

• Automotive Systems: ECU load driving, lighting control, and solenoid actuation.
• Industrial Automation: PLC output modules, relay replacements, and motor drivers.
• Power Distribution: Multi-channel load switching in HVAC, robotics, and test equipment.
• Safety-Critical Systems: Fault-protected designs requiring auto-recovery from overloads.

Conclusion of VN808-E

The VN808-E stands out for its high channel count, low power dissipation, and integrated protections, reducing external component count and board space. Its wide operating range and diagnostic features make it a superior choice for harsh environments compared to discrete solutions. Engineers benefit from STMicroelectronics' VIPower™ technology, ensuring reliability in automotive, industrial, and power management applications.
