DC MOTOR DRIVER IC

TA7259P/P(LB)/F TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA7259P,TA7259P(LB),TA7259F DC MOTOR DRIVER IC The TA7259P is a 3−phase Bi−directional motor driver IC. It designed for use VTR tape deck, floppy disk and record player motor drivers. It contains output power drivers, position sensing circuits, control amplifier and CW / CCW control circuit. 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. Weight HDIP14−P−500−2.54A : 3.00 g (Typ.) HSOP14−P−2.54 : 3.00 g (Typ.)
