AMT49502
Description
The AMT49502 is an N-channel power MOSFET driver capable of controlling MOSFETs connected in a half-bridge arrangement and is specifically designed for automotive applications with high-power inductive loads, such as brush DC motors, BLDC motors, VR/SR motors, solenoids, and actuators. A unique charge pump regulator provides full gate drive over the full supply voltage range from 5.5 to 80 V for most applications.
