DRV8825 具有片上 1/32 微步进分度器的 2.5A 双极步进电机驱动器（Step/Dir 控制器）
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).
A simple step/direction interface allows easy interfacing to controller circuits. Pins allow configuration of the motor in full-step up to 1/32-step modes. Decay mode is programmable.
Internal shutdown functions are provided for overcurrent protection, short circuit protection, undervoltage lockout and overtemperature
