Overview
The DRV8824PWPR is a bipolar stepper motor driver manufactured by Texas Instruments, housed in a 28-pin HTSSOP package. It operates within a supply voltage range of 8.2 V to 45 V and delivers an output current of 1.6 A per bridge. The device supports step resolutions from full step to 1/32 microstepping via mode pins. It features a simple Step/Dir interface, configurable decay modes, and a low-power sleep mode. Operating temperatures range from -40°C to +85°C.
Feature Summary
- Integrated half-bridge power stage with on-chip control logic for bipolar stepper motors
- Configurable microstepping resolution ranging from full step to 1/32
- Built-in protection mechanisms including overcurrent, short-circuit, undervoltage lockout, and thermal shutdown
Applications
- Printer and scanner motion control systems
- Industrial automation equipment
- Office automation devices requiring precise positioning
Procurement Notes
Verify the specific suffix 'PWPR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 28-HTSSOP footprint matches the target PCB layout dimensions. Ensure the operating environment remains within the specified -40°C to +85°C temperature range to maintain rated performance and reliability standards.
Selection Notes
Select this component when driving bipolar stepper motors with currents up to 1.6 A at voltages up to 45 V. It is suitable for applications requiring high-resolution microstepping and integrated fault protection. Consider thermal management requirements if continuous operation near maximum current ratings is expected in enclosed environments.
Part Context
This part belongs to the DRV8824 series of motor drivers designed for cost-effective and compact stepper motor solutions. It integrates both the power MOSFETs and control circuitry into a single package, reducing external component count. The PWPR designation indicates the reel-packaged version of the standard PWP tube variant.
Replacement Considerations
The DRV8824PWP is the non-reel equivalent offering identical electrical characteristics. For higher current capabilities, consider the DRV8825 series. Verify pin compatibility before substituting with other stepper drivers in the same family.
