Three-phase Brushless
Motor Pre-drivers for Paper Feed
BD6761FS,BD6762FV
No.10016EAT01
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).
Features
1) Predriver for high-side/low-side N-channel MOS-FET
2) Built-in booster (step-up) circuit
3) Built-in FG and hysteresis amplifiers
4) Built-in current limit circuit
5) Built-in thermal shutdown circuit
6) Built-in forward/reverse rotation switching circuit (BD6761FS, FD6762FV)
7) Built-in short brake circuit (BD6761FS, BD6762FV)
8) Built-in low voltage protection circuit (BD6761FS, BD6762FV)
9) Built-in speed lock detection circuit (BD6762FV)
10) Built-in motor lock protection circuit (BD6762FV)
11) Built-in start-stop circuit (BD6762FV)
12) Built-in servo circuit (Speed discriminator + PLL) (BD6762FV)
13) Built-in frequency multiplication circuit (BD6762FV)
14) 180°, direct PWM drive (BD6761FS)
15) 120°, slope switchable direct PWM drive (BD6762FV)
