VNH7100ASTR

Overview

The VNH7100ASTR is an automotive fully integrated H-bridge motor driver manufactured by STMicroelectronics. It utilizes VIPower M0 technology to integrate Power MOSFETs with intelligent protection circuitry on a single die. The device operates within a supply voltage range of 4 V to 28 V and supports a continuous output current of 15 A. It features PWM control up to 20 kHz for speed regulation and includes diagnostic functions such as MultiSense analog current feedback. The component is housed in a SOIC-16 package and is qualified to the AEC-Q100 standard.

Feature Summary

• Integrates dual monolithic high-side drivers and two low-side switches using proprietary VIPower M0 technology
• Provides comprehensive protection including thermal shutdown, overvoltage clamp, cross-conduction protection, and short-to-ground/VCC detection
• Supports direct microcontroller interfacing via 3 V CMOS-compatible inputs for direction and brake control
• Enables analog motor current monitoring through the MultiSense pin delivering current proportional to load

Applications

• Automotive DC brush motor control
• Solenoid driving applications
• Valve actuation systems
• Fan and pump control in vehicle environments

Procurement Notes

Verify the specific suffix 'A' against the official datasheet to confirm exact ordering options and availability status. Note that distribution channels may indicate discontinuation or limited stock for this specific variant. Ensure compliance with AEC-Q100 requirements if used in certified automotive assemblies. Cross-reference the SOIC-16 package dimensions and thermal characteristics during PCB layout design to ensure proper heat dissipation.

Selection Notes

Select this component for applications requiring a robust, single-chip solution for high-current DC motor control in automotive environments. The integrated protection features reduce external component count compared to discrete solutions. Consider the 15 A output capability and 28 V maximum voltage rating when sizing for specific loads. The MultiSense feature is critical for applications requiring closed-loop current monitoring without additional sensing hardware.
