AM2021中文资料Three Channel Half H-Bridge Driver数据手册AMtek规格书

描述 Description

The AM2021 provides three individually controllable half-H-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 loads. Each output driver channel consists of N-channel power MOSFETs in a half-H-bridge configuration.

The AM2021 Can supply up to 5.5A peak or 2A RMS output current per channel (with proper PCB heat sink at 10V and 25℃) per half-H-Bridge.

The Device provides internal shutdown functions for Short-circuit protection, over current and over temperature protection.
