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.

(PWM frequency, Overcurrent protection limit, Start time and Lock protection)
