TIDRV8711DCPR
Overview
The DRV8711DCPR is a highly configurable bipolar stepper motor controller designed to drive external N-channel MOSFETs. It supports a wide supply voltage range from 8V to 52V and features an integrated 1/256-step microstepping indexer to provide smooth motion profiles. The device is controlled via an SPI interface, allowing engineers to fine-tune torque, decay modes, and stall detection parameters for specific motor characteristics.
Why Choose This Part
The use of external MOSFETs provides the flexibility to drive motors with significantly higher current than integrated drivers while maintaining a small 38-HTSSOP footprint. Its integrated stall detection and BEMF output simplify system design by reducing the need for external sensors or encoders.
Applications
Key Specifications
Getting Started
Evaluation can begin with the DRV8711EVM module, which provides a complete reference design including the controller and power stage. Developers should use the SPI interface to configure the torque DAC and select between Step/Direction or PWM control modes as defined in the datasheet.
