Three-phase motor pre-driver for LBP
BA6680FS
Description
BA6680FS is a three-phase motor pre-driver.
PWM driving system is adopted in this IC as
well as incorporation of a booster to drive
N-channel (upper and lower) MOS FET.
Current limit, FG amplifier, FG hysteresis
amplifier and charge-pump are incorporated
as other functions.
Features
1)Three-phase motor pre-driver
2)Upper and lower N-channel MOS FET driving
3)PWM driving
4)Built-in charge-pump circuit
5)Built-in FG amplifier and hysteresis amplifier
6)Built-in current limit circuit
