Three Phase Motor Predriver IC for automotive
Built-in the Phase adjustment control and
180°energizing drive
Three Phase Motor Predriver
BD16805FV-M
General Description
BD16805FV-M is three phase motor driver for air conditioner blower motor, battery cooling fan motor, and seat cooling fan
motor. This IC can implement silent drive by 180° energizing drive. The BD16805FV includes a built-in phase adjustment
control function to drive highly effective. The setting that can correspond to various motor controls is possible.
