BA6680FS

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.
