FEATURES
l 3−phase Bi−directional driver and output current up to ±1.2 A. l Few external parts required. l Wide operating supply voltage range: VCC (opr.) MIN. = 7 V l Forward and reverse rotation is controlled simply by means of a
CW / CCW control signal fed into FRS. l High sensitivity of position sensing amplifier.
(VH = 10 mV (Typ.), recommend to use TOSHIBA Ga−As hall sensor “THS” series. l Surge protect diode connected for all input terminals. (Position sensing, control, CW / CCW control inputs.) l DIP−14F power package.
