DRV8462DDVR

Overview

The DRV8462DDVR is a dual H-bridge stepper motor driver from Texas Instruments, designed for high-performance applications requiring robust power handling. It features an integrated MOSFET power stage capable of delivering up to 10A full-scale current per bridge with low on-resistance. The device supports a wide supply voltage range from 4.5V to 65V and includes an internal current regulation system with ±5% accuracy. Key functional parameters include a step resolution capability of 1/256 microstepping, a logic supply voltage of 3.05V to 5.5V, and an operating temperature range of -40°C to 125°C. It utilizes a 44-PowerTSSOP package.

• Medical imaging equipment and diagnostic devices
• Textile machinery and sewing machines
• Automated teller machines (ATMs) and currency counters

Procurement Notes

Verify the specific suffix 'DDVR' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure that the required output current and supply voltage levels align with the component's rated specifications. Confirm that the design accommodates the necessary thermal management for the PowerTSSOP package under maximum load conditions.

Selection Notes

Select this component when a dual H-bridge solution with high current capacity and integrated control is required. It is suitable for designs needing precise microstepping without external microcontroller overhead. Consider the 44-pin package size and thermal requirements relative to the PCB layout constraints and ambient operating temperatures of the target application environment.
