Procurement Notes
Verify the specific ordering suffix matches the required tape and reel quantity. Confirm that the AEC-Q100 qualification status aligns with your automotive grade requirements. Ensure the 16-SOIC package dimensions fit your PCB layout constraints. Check for any recent product change notices regarding material or assembly sources before finalizing procurement.
Selection Notes
Select this component when a robust, single-chip solution for high-current brushed DC motor control is needed. It is appropriate for applications requiring integrated diagnostics and low quiescent current. Consider the 15A continuous current rating and thermal performance under your specific operating conditions. Ensure compatibility with 3V CMOS input logic levels for microcontroller interfacing.
Part Context
The VNH7070ASTR belongs to the VIPower M0-7 family of smart high-side and H-bridge drivers. This series is engineered for automotive environments, offering high reliability and extensive protection features. It simplifies design by integrating gate drivers, logic, and power stages into a single package, reducing component count and board space compared to discrete solutions.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult official STMicroelectronics resources for potential alternatives within the VIPOWER family.
