AMT49101 Description
The AMT49101 is an N-channel power MOSFET driver capable of controlling MOSFETs connected in a 3-phase bridge arrangement and is specifically designed for 48 V automotive power applications with high-power inductive loads, such as BLDC motors. A fixed-frequency buck converter provides a regulated gate drive and bootstrap charge voltage over the full supply voltage range from 10 to 80 V. A bootstrap capacitor is used...
