• Integrates four fully protected high-side switches for independent motor control
• Includes comprehensive diagnostic capabilities and protection against short circuits and overloads
• Optimized for automotive environments with wide operating temperature tolerance

Applications

• Automotive body electronics systems
• Brushed DC motor actuation in vehicles
• Ignition system controllers

Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm the specific suffix and revision level matches design requirements. Check for end-of-life status or alternative recommendations directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when designing automotive circuits requiring four isolated high-side outputs. Ensure the load current does not exceed the 9A limit per channel. Verify that the SO-28 package fits the PCB layout constraints and thermal management strategy.

Part Context

This part belongs to the VN770 series of smart power devices designed for robust motor driving applications. It serves as a specialized solution for managing multiple actuators within constrained automotive electrical architectures, offering integrated protection and diagnostics.

Replacement Considerations

Check for direct substitutes within the VN770 family such as the VN770KP-E or VN770KTR-E. Verify pin compatibility and electrical specifications before substitution.
