DRV8813 具有 4 级电流调节的 2.5A 双极步进电机驱动器（PH/EN 控制器）

The DRV8813 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 DRV8813 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 parallel digital control interface is compatible with industry-standard devices. Decay mode is programmable.

Internal shutdown functions are provided for over current protection, short circuit protection, under voltage lockout and overtemperature
