DRV8434PWPR Description

Short technical summary and product information.

The DRV8434PWPR from Texas Instruments is a highly integrated stepper motor driver designed for industrial and consumer applications. It features a simple STEP/DIR interface and supports microstepping up to 1/256 for precise motor control.

 

Key electrical specifications include a wide operating supply voltage range of 4.5V to 48V and a high current capacity of 2.5A full-scale, with an RMS current of 1.8A. The device incorporates integrated current sensing, eliminating the need for external sense resistors and saving PCB space. It offers configurable PWM chopping off-times and supports multiple decay modes, including Smart tune, slow, and mixed decay options.

 

This driver is housed in a 28-HTSSOP package with a surface mount type. It operates within a temperature range of -40°C to 125°C. Protection features such as undervoltage lockout, overcurrent protection, and thermal shutdown are included for enhanced reliability.

 

Applications for the DRV8434PWPR include printers, scanners, ATM machines, textile machines, stage lighting, office and home automation, factory automation, robotics, medical applications, and 3D printers.
