VNH7040AYTR

Overview

The VNH7040AYTR is an automotive-grade, fully integrated H-bridge motor driver manufactured by STMicroelectronics. It incorporates a dual monolithic high-side driver and two low-side switches built on VIPower M0 technology. The device supports a supply voltage range of 4 V to 28 V and delivers an output current of 35 A. It operates within a junction temperature range of -40°C to +150°C and accepts PWM signals up to 20 kHz for speed control. The component is housed in a PowerSSO-36-TP package with exposed die pads for thermal optimization and holds AEC-Q100 qualification.

Feature Summary

• Integrates dual high-side drivers and two low-side switches on a single die using proprietary VIPower M0 technology
• Provides MultiSense diagnostic feedback including proportional motor current sensing, chip temperature monitoring, and battery voltage feedback
• Features comprehensive protection mechanisms such as cross-conduction prevention, overtemperature shutdown, and configurable latch-off

Applications

• Automotive brushed DC motor control
• Vehicle body electronics actuation
• Power window and seat adjustment systems

Procurement Notes

Verify the specific suffix 'AYTR' corresponds to the required tape-and-reel packaging configuration. Confirm that the PowerSSO-36-TP package variant matches the thermal management requirements of the target PCB layout. Ensure compatibility with the intended microcontroller interface levels before finalizing procurement specifications.

Selection Notes

Select this component when a robust, single-chip solution for bidirectional motor control is required in harsh automotive environments. The integrated MultiSense functionality simplifies system design by eliminating external current sensing resistors. Consider the exposed pad thermal performance for applications requiring sustained high-current operation without additional heatsinking infrastructure.
