VN772KP-E

Overview

The VN772KP-E is a quad smart power solid-state relay designed for complete H-bridge configurations, manufactured using STMicroelectronics VIPower M0-3 technology. It integrates three monolithic chips within a standard SO-28 package, comprising two high-side and two low-side switches. The device supports a supply voltage range of 5.5V to 36V with a typical on-resistance of 125mOhm and a continuous output current of 9A per channel. It features AEC-Q100 automotive qualification and operates within a junction temperature range of -40°C to 150°C.

Feature Summary

• Integrates dual high-side and dual low-side switches in a single SO-28 package for compact H-bridge designs
• Includes built-in thermal shutdown and linear current limiting for short-circuit protection
• Provides status flag diagnostics via open-drain output for overtemperature and open-load detection
• Features integrated clamping circuits and undervoltage lockout for robust system reliability

Applications

• Brushed DC motor driving in automotive bridge configurations
• General-purpose low-voltage switching applications
• Relay driver circuits requiring smart power integration

Procurement Notes

Verify component authenticity through authorized channels as the VN772KP-E is officially obsolete. Confirm that replacement sources provide valid traceability documentation. Ensure compatibility with existing PCB footprints and thermal management requirements when transitioning to alternative components. Review end-of-life notifications for specific discontinuation timelines and last-time buy windows.

Selection Notes

Select this component only if legacy design compatibility with the SO-28 package and VIPower M0-3 architecture is required. Evaluate whether newer generations offer improved thermal performance or lower on-resistance. Consider the availability of equivalent quad smart power devices from other manufacturers if redesign flexibility exists. Assess the long-term support implications of using an obsolete part number.
