VN5770AK-E

Overview

The VN5770AK-E is a quad smart power solid state relay designed for complete H-bridge configurations. It integrates three monolithic chips within a standard SO-28 package, comprising a double high-side switch and two low-side switches. The high-side components utilize VIPower M0-5 technology, while the low-side switches employ fully protected VIPower M0-3 OMNIFET II architecture. This device supports DC motor driving in bridge configurations or acts as a quad switch for low-voltage applications. It features AEC-Q100 automotive qualification and ECOPACK compliance.

Feature Summary

• Integrates dual high-side and dual low-side switches using distinct VIPower technologies for optimized performance
• Provides proportional analog current sense feedback for load monitoring and diagnostic purposes
• Includes comprehensive protection mechanisms such as thermal shutdown with hysteresis and active inrush current management
• Offers fault indication through voltage flags on high-side and current sink flags on low-side switches

Applications

• DC motor drive in H-bridge configurations
• Quad switch control for low-voltage applications
• Automotive body and convenience systems

Procurement Notes

Verify component status carefully as this part may be marked as Not Recommended for New Designs (NRND) or discontinued depending on the specific suffix variant. Confirm availability through authorized distributors as stock levels are restricted. Ensure that the selected package type matches the required PCB footprint and that all relevant datasheet revisions are consulted for accurate pinout and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when a single IC solution is required to manage both high-side and low-side switching for H-bridge topologies. The integration of different VIPower technologies allows for tailored protection levels between high and low sides. Consider the analog current sense capability if precise load monitoring is necessary without external sensing resistors. Verify that the operating temperature range and voltage specifications align with the target system requirements.

Part Context

This device belongs to the VN577x family of smart power switches from STMicroelectronics. It is part of the VIPower portfolio, which combines power MOSFETs with control and protection circuits on a single chip. The family is widely used in automotive applications due to its robustness and diagnostic capabilities. The VN5770 specifically addresses the need for integrated H-bridge control in a compact form factor.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official STMicroelectronics resources for potential obsolescence notices or recommended alternative devices within the VIPower family.
