Overview
The DRV8806PWPR is a unipolar stepper motor driver manufactured by Texas Instruments, designed for applications requiring integrated control and power stages. It operates within a supply voltage range of 8.2V to 40V and delivers an output current of 2A. The device utilizes DMOS technology and features a 16-HTSSOP package with surface-mount installation. It supports a junction temperature range from -40°C to +85°C and includes protection mechanisms such as overcurrent protection and thermal shutdown. The component is RoHS3 compliant and has a moisture sensitivity level of 3.
Feature Summary
- Integrated full-bridge driver architecture for unipolar stepper motors
- Built-in overcurrent protection and thermal shutdown circuitry
- Low standby current consumption for power efficiency
- Compatible with standard microcontroller logic interfaces
Applications
- Unipolar stepper motor control in industrial automation systems
- Motion control modules for office equipment and printers
- Solenoid driving applications in automotive or consumer devices
- General-purpose motor driver circuits in embedded systems
Procurement Notes
Verify the specific suffix 'PWPR' corresponds to the tape-and-reel packaging format when ordering. Confirm that the 16-HTSSOP footprint matches the target PCB design guidelines provided in the mechanical drawings. Ensure compliance with RoHS3 standards if required by project specifications. Check moisture sensitivity level (MSL 3) requirements for reflow soldering profiles during assembly planning.
Selection Notes
Select this component for unipolar stepper motor applications requiring up to 2A continuous current. Consider the 8.2V to 40V input voltage range for compatibility with system power supplies. Evaluate the 16-pin HTSSOP package size against available board space. Compare thermal performance characteristics against expected ambient temperatures and heat dissipation capabilities of the host system.
Part Context
The DRV8806 belongs to Texas Instruments' DRV88xx series of motor drivers, which are designed for low-cost, high-performance stepper motor control. This series integrates both logic and power sections into a single package, reducing external component count. The PWPR variant specifically denotes the reel-packaged version suitable for automated surface-mount assembly processes.
Replacement Considerations
Direct pin-to-pin replacements may include other DRV88xx series devices with similar current ratings, such as the DRV8803 or DRV8804, depending on specific voltage and current requirements. Verify electrical parameters and package dimensions before substitution.
