DRV8881PPWPR

Overview

The DRV8881PPWPR is a bipolar stepper motor driver and dual H-bridge controller manufactured by Texas Instruments. It operates within a supply voltage range of 6.5 V to 45 V, supporting a maximum output current of 2.5 A per channel. The device features an integrated power MOSFET half-bridge architecture with four outputs. It functions at a switching frequency of 100 kHz and maintains a quiescent supply current of 8 mA. The component is housed in a 28-HTSSOP package suitable for surface mount installation. It supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates full control logic and power stage for bipolar stepper or dual H-bridge applications
• Utilizes parallel interface for direct connection to microcontroller systems
• Employs power MOSFET technology for efficient half-bridge output configuration

Applications

• Bipolar stepper motor control systems
• Dual H-bridge motor drive circuits
• General purpose motion control applications

Procurement Notes

Verify the specific suffix PPWPR against the official datasheet to confirm the tape and reel packaging format. Ensure compatibility with the required 28-HTSSOP footprint during PCB layout. Confirm that the 6.5 V to 45 V supply range aligns with the target system voltage. Check for moisture sensitivity level requirements and appropriate storage conditions prior to assembly.

Selection Notes

Select this component when a high-voltage stepper driver with integrated power stages is required. The 2.5 A current rating suits moderate load applications. Consider the 28-pin HTSSOP package constraints for board space. Verify thermal management needs given the operating temperature limits. Compare against lower voltage alternatives if the system operates below 6.5 V.
