The A4918 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 7 V and allows the A4918 to operate with a reduced gate drive down to 4.5 V.
Gate drive voltage and strength are programmable to help reduce EMC issues.
