产品概览
The DRV8880PWPR from Texas Instruments is a 45V, 2A bipolar stepper motor driver with smart tune auto-tuning, 1/16 microstepping, and STEP/DIR interface in a 28-pin HTSSOP PowerPAD package. It integrates two N-channel MOSFET H-bridges with adaptive blanking time for smooth stepping performance.
