Description
The AM2789 provides three individual controllable half-bridge drivers. The device is intended to drive a three-phase brushless DC motor, though it can also be used to drive solenoids or other types of load. Each output driver channel consists of P-channel +N-channel power MOSFETs in a half-bridge configuration.
The AM2789 can supply up to 6A peak or 3.5A continuous output current per channel (with proper PCB heat sink at 10V and 25℃) per half-Bridge. There is internal shutdown function for over-temperature protection.
The device provides internal shutdown functions for Short-circuit protection, turbo current limit and over temperature protection.
