Overview
The DRV8880RHRR is a dual half-bridge stepper motor driver manufactured by Texas Instruments, housed in a WQFN-28 package. It supports bipolar stepper motors with an output current of 2 A and operates within a supply voltage range of 6.5 V to 45 V. The device features integrated charge pumps for gate drive and includes protection mechanisms such as overcurrent protection, thermal shutdown, and under-voltage lockout. It functions at switching frequencies up to 100 kHz and operates across a temperature range of -40°C to +125°C.
Feature Summary
- Integrated charge pump architecture eliminates the need for external bootstrap components
- Built-in self-tuning capability optimizes step performance automatically
- Comprehensive protection suite including overcurrent detection and thermal shutdown
Applications
- Bipolar stepper motor control in industrial automation systems
- Motion control modules for office equipment
- Precision positioning drives in medical devices
Procurement Notes
Verify the specific suffix RHRR corresponds to the WQFN-28 package and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure input voltage limits are respected during system design to prevent device damage.
Selection Notes
Select this component for applications requiring compact dual half-bridge solutions with integrated charge pumps. Compare against DRV8881 or DRV8884 if higher current ratings or different voltage tolerances are required. Evaluate thermal management needs based on the 2 A continuous output capability and ambient operating conditions.
Part Context
This part belongs to the DRV888x family of stepper motor drivers from Texas Instruments. These devices are designed for cost-sensitive, space-constrained applications requiring reliable bipolar stepper motor control. The family shares common architectural features such as integrated charge pumps and protection circuits.
Replacement Considerations
DRV8881ERHRR offers similar functionality with higher current capacity. DRV8884RHRR provides comparable performance with slight variations in voltage tolerance. Verify pin compatibility and electrical specifications before substitution.
