VNQ810-E

Power Distribution Switches, Load Drivers Overview

The VNQ810-E is a monolithic quad high-side driver implemented in STMicroelectronics VIPower M0-3 technology. It integrates four independent N-channel outputs within a single SOIC-28 package, effectively combining two VND810 units. The device supports load voltages from 5.5 V to 36 V with a typical on-resistance of 160 mΩ and a maximum output current of 3.5 A per channel. It operates across an extended junction temperature range of -40°C to +150°C and includes comprehensive protection features such as overtemperature shutdown, overvoltage protection, and open-load detection.

Power Distribution Switches, Load Drivers Feature Summary

• General purpose load switching in vehicle electronics

Power Distribution Switches, Load Drivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches project requirements. Check for end-of-life status and availability of alternative sources. Ensure compliance with RoHS directives if required by the application. Validate packaging type against assembly line specifications.

Power Distribution Switches, Load Drivers Selection Notes

Select this component for applications requiring multiple high-side switches in a limited board space. Consider the 36 V rating for standard automotive loads. Evaluate thermal management needs given the 150°C junction limit. Verify that the SOIC-28 footprint fits the design constraints. Ensure input logic levels are compatible with the non-inverting interface.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the VIPower M0-3 family, designed for robust automotive environments. It serves as a consolidated solution for driving inductive and resistive loads. The integration reduces bill-of-materials count compared to discrete solutions. It is distinct from lower-power variants in the same series.

Power Distribution Switches, Load Drivers Replacement Considerations

The VNQ810 is noted as being formed by assembling two VND810 chips. Verify pin compatibility if substituting with individual VND810 components. Check datasheets for any differences in protection thresholds or thermal characteristics between the integrated and discrete versions.
