Overview
The DRV8811PWP is a bipolar stepper motor driver manufactured by Texas Instruments, housed in a 28-pin HTSSOP package. It supports an operating supply voltage range of 8 V to 38 V and delivers a maximum output current of 1.4 A per coil. The device features a low quiescent supply current of 4 mA and operates within a temperature range of -40°C to +85°C. It integrates full-bridge drivers with two outputs for precise stepper motor control.
Feature Summary
- Integrates full-bridge power stages with integrated control logic for simplified system design
- Supports multiple step resolutions including full, half, quarter, eighth, sixteenth, and thirty-second steps
- Includes adjustable current limit control and overcurrent protection mechanisms
Applications
- Bipolar stepper motor positioning systems
- Office automation equipment such as printers and scanners
- Security access control mechanisms
Procurement Notes
Verify the specific suffix PWP indicates the tube packaging variant rather than the PR reel version. Confirm the datasheet revision matches your design requirements. Ensure thermal management solutions are adequate for the HTSSOP-28 package given the 1.4 A output capability. Check for RoHS compliance status on the official manufacturer documentation before finalizing procurement.
Selection Notes
Select this component when a compact solution for bipolar stepper motors is required with integrated power stages. It is suitable for applications needing fine microstepping resolution up to 1/32 step. Consider the 38 V maximum supply voltage and 1.4 A current limit against load requirements. Compare against the DRV8811PWPR if reel packaging is preferred for automated assembly processes.
Part Context
This part belongs to the DRV8811 family of stepper motor drivers from Texas Instruments. It shares core functionality with variants like DRV8811PWPR but differs in packaging format. The series is designed for cost-effective motion control applications requiring reliable performance in consumer and industrial electronics environments.
Replacement Considerations
Direct substitutes include DRV8811PWPR for identical electrical specifications with different packaging. Evaluate DRV8811EVM for evaluation purposes during development phases.
