Product Introduction

Overview

The DRV8811PWPR, produced by Texas Instruments, is a highly integrated stepper motor driver designed for controlling bipolar stepper motors. This device is part of the DRV8811 family and is packaged in a thermally enhanced 28-pin HTSSOP package with an exposed thermal pad. It provides a comprehensive solution for applications requiring precise motor control, such as printers, scanners, office automation machines, gaming machines, factory automation, and robotics.

The DRV8811PWPR features two H-bridge drivers and a built-in microstepping indexer, allowing for up to 1/8-step microstepping. It supports step and direction control through a simple STEP-and-DIR interface, making it easy to integrate with controller circuits. The device also includes programmable mixed decay, blanking, and off-time settings to accommodate various motor requirements.

Q & A

  1. What is the operating supply voltage range of the DRV8811PWPR?

    The operating supply voltage range is 8 V to 38 V.

  2. What is the maximum current per winding that the DRV8811PWPR can handle?

    The maximum current per winding is 1.9 A.

  3. What microstepping capabilities does the DRV8811PWPR offer?

    The device supports up to 1/8-step microstepping.

  4. What type of package does the DRV8811PWPR come in?

    The device is packaged in a 28-pin HTSSOP package with an exposed thermal pad.

  5. What protection features are included in the DRV8811PWPR?

    The device includes VM undervoltage lockout (UVLO), overcurrent protection (OCP), and thermal shutdown (TSD).

  6. How does the DRV8811PWPR handle current regulation?

    The device uses PWM chopping current regulation, with the current set by a comparator comparing the voltage across a current-sense resistor with a reference voltage.

  7. What is the purpose of the STEP and DIR pins on the DRV8811PWPR?

    The STEP and DIR pins are used for step and direction control, allowing easy interfacing to controller circuits.

  8. Can the DRV8811PWPR be put into a low-power sleep mode?

    Yes, the device includes a low-power sleep mode to minimize power consumption when the system is idle.

  9. How does the DRV8811PWPR handle overcurrent conditions?

    Overcurrent conditions are sensed in both directions, and the device shuts down in case of an overcurrent event, resetting the microstepping indexer to the home state.

  10. What happens if the die temperature exceeds safe limits in the DRV8811PWPR?

    If the die temperature exceeds safe limits, all drivers in the device are shut down, and the indexer is reset to the home state. Operation resumes once the temperature falls to a safe level.
