DESCRIPTION
The AMT49106 is an N-channel power
MOSFET driver capable of controlling
MOSFETs connected in a 3-phase bridge arrangement and is specifically designed for automotive applications with high-power inductive loads, such as BLDC motors.
A unique charge pump regulator provides the supply for the
MOSFET gate drive for battery
voltages down to 5.5 V and allows the AMT49106 to operate with a ...
