DRV8825PWPR 电机驱动芯片

DRV8825 DESCRIPTION

The DRV8825 provides an integrated motor driver solution for printers, scanners, and other automated

equipment applications. The device has two H-bridge drivers, and can drive a bipolar stepper motor or two DC

motors. The output driver block for each consists of N-channel power MOSFET’s configured as full H-bridges to

drive the motor windings. The DRV8825 can supply up to 2.5-A peak or 1.75-A RMS output current (with proper heatsinking at 24 V and 25°C).
