Motor Drivers for Printers

Three-phase Brushless

Motor Pre-drivers for Paper Feed

BD6761FS,BD6762FV

●

Description

This product is the motor predriver for high-side/low-side N-channel MOS-FET drive, which has the built-in booster (step-up)

circuit. BD6761FS uses the drive type controlled by the servo signal input from outside and BD6762FV incorporates a servo

circuit (Speed discriminator + PLL servo).
