Overview
The DRV8711DCP is a stepper motor controller manufactured by Texas Instruments, designed to drive bipolar stepper motors or two brushed DC motors using external N-channel MOSFETs. It integrates a microstepping indexer supporting resolutions from full step to 1/256th step. The device operates on a supply voltage range of 8 V to 52 V and features an output current capability of 200 mA. It functions within a temperature range of -40°C to +85°C and utilizes a 38-HTSSOP surface-mount package.
Feature Summary
- Integrates a microstepping indexer for precise motion control
- Supports adaptive blanking and programmable current chopping
- Enables flexible interface via SPI or Step/Direction inputs
Applications
- Bipolar stepper motor positioning systems
- Two brushed DC motor control applications
- Industrial automation equipment requiring precise motion
Procurement Notes
Verify the specific suffix 'DCP' against the official datasheet to confirm the tube packaging variant versus the 'DCPR' reel variant. Ensure the selected component matches the required thermal performance and pinout configuration for the target PCB layout. Cross-reference the manufacturer's latest documentation to confirm active status and any potential design changes.
Selection Notes
Select this component when designing systems requiring high-resolution microstepping up to 1/256 steps with external power stages. It is suitable for applications needing a compact solution with integrated logic control and current regulation. Consider the 38-pin HTSSOP package constraints and the requirement for external MOSFETs when evaluating board space and bill of materials.
Part Context
This part belongs to the DRV8711 family of stepper motor controllers from Texas Instruments. It serves as a dedicated driver IC that manages the complex timing and current regulation tasks for external power switches. The family is engineered for applications demanding smooth motor operation and high positional accuracy in constrained environments.
