DRV8805 具有片上分度器的 1.5A 单极步进电机驱动器（Step/Dir 控制器）
The DRV8805 provides an integrated solution for driving unipolar stepper motors. It includes four low side drivers with overcurrent protection and provides built-in diodes to clamp turn-off transients generated by the motor windings.
Indexer logic to control a unipolar stepper motor using a simple step/direction interface is also integrated. Three stepping modes are supported: 2 phase (full-step), 1-2 phase (half-step), and 1-phase (wave drive).
The DRV8805 can supply up to 1.5-A (single channel on) or 800-mA (four channels on) continuous output current (with adequate PCB heatsinking at 25°C).
Internal shutdown functions are provided for over current protection, short circuit protection, under voltage lockout and overtemperature and faults are indicated by a fault output pin
