DRV8829 具有 32 级电流调节的 5A 半双极步进电机驱动器（PH/EN 控制器）
The DRV8829 provides an integrated motor driver solution for DC and stepper motors used in cash handling machines and other automated equipment applications. The device has one H-bridge driver, and can drive one winding of a bipolar stepper motor or one DC motor. The output driver block consists of N-channel power MOSFET’s configured as a single full H-bridge to drive the motor winding. The DRV8829 can supply up to 5-A peak or 3.5-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 overcurrent protection, short circuit protection, undervoltage lockout and overtemperature
