Key Features
- 8-channel high-side driver with 0.5 A per output, built-in overcurrent shutdown, thermal protection, and transient clamp for driving relays, lamps, and solenoids directly from a 12 V automotive bus
- SPI serial interface controls all 8 channels and reads back diagnostic fault status, enabling full load management and fault detection with only 4 microcontroller I/O pins instead of 8 discrete GPIO outputs
- 36-pin PowerSO package with integrated thermal resistance benefits, supporting continuous operation over −40°C to 150°C junction temperature range for under-hood automotive body-control module applications
Applications
The VN808SR is designed for automotive body-control modules, industrial PLC output stages, and smart relay replacement circuits where 8 independent 12 V load channels—such as lamps, solenoids, relays, and heater elements—must be controlled and monitored from a single SPI-connected microcontroller. Its integrated protection features eliminate discrete fuse and clamping components, reducing BOM count and improving system reliability in harsh automotive environments subject to load-dump transients and temperature extremes.

Frequently Asked Questions
What is the per-channel output current rating of the VN808SR and which load types can it drive directly?
Each of the 8 channels in the VN808SR can source up to 0.5 A continuously, sufficient to drive automotive lamps up to 6 W at 12 V, small relays with 200 mA coil current, or solenoid valves rated below 0.5 A without external transistors. Overcurrent protection triggers at approximately 0.7 A per channel, disconnecting the output within 10 µs to prevent damage to the driver or wiring harness.
How does the SPI interface of the VN808SR reduce microcontroller I/O pin usage in an 8-channel system?
The VN808SR uses a 4-wire SPI bus (MOSI, MISO, SCLK, CS) to control all 8 output channels and read back diagnostic registers, replacing 8 individual GPIO output pins plus 8 feedback lines that a discrete MOSFET solution would require. Daisy-chaining multiple VN808SR devices on the same SPI bus scales the system to 16 or 24 channels using only 4 microcontroller pins plus one CS line per device.
Which protection features in the VN808SR eliminate external component requirements in automotive load-switching designs?
The VN808SR integrates 4 protection mechanisms: overcurrent shutdown (triggers above 0.7 A), thermal shutdown (activates near 150°C junction), under-voltage lockout (disables outputs below approximately 4 V supply), and transient clamp for ISO 7637 load-dump pulses up to 40 V. These built-in protections replace external fast-blow fuses, TVS diodes, and NTC thermistors that a discrete MOSFET driver circuit would require, reducing BOM by at least 8 passive components in an 8-channel design.
