VNH5050ATR-E

Overview

The VNH5050ATR-E is a fully integrated H-Bridge motor driver designed for automotive applications, utilizing STMicroelectronics' VIPower®M0-5 technology. It incorporates dual monolithic high-side drivers and two low-side switches on isolated lead frames within a PowerSSO-36 TP package. The device supports brushed DC motors with an output current of 30 A and operates at supply voltages between 5.5 V and 18 V. It features PWM control up to 20 kHz, 3 V CMOS compatible inputs, and comprehensive protection including thermal shutdown, overvoltage clamp, and cross-conduction prevention.

Feature Summary

• Fully integrated H-Bridge configuration combining power MOSFETs and intelligent protection circuitry
• Direct microcontroller interface via 3 V CMOS compatible input signals
• Integrated diagnostic feedback through digital DIAG pins
• Current sensing capability with proportional output signal

Applications

• Automotive body and convenience systems
• Brushed DC motor control in vehicles
• Prototype development using dedicated evaluation boards

Procurement Notes

Verify the specific suffix 'TR-E' to confirm tape-and-reel packaging and RoHS compliance status. Confirm that the component meets AEC-Q100 automotive grade requirements if used in production environments. Check for any recent Product Change Notifications (PCN) regarding assembly or material changes. Ensure the design accounts for the exposed die pad thermal management provided by the PowerSSO-36 package.

Selection Notes

Select this component for applications requiring a single-chip solution for bidirectional motor control. It is suitable where space constraints favor the compact PowerSSO-36 TP package over discrete solutions. Consider the 30 A output capability and integrated protections when designing for harsh automotive electrical environments. Verify compatibility with existing microcontroller logic levels due to the 3 V CMOS input requirement.
