TA7736P/F
TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA7736P,TA7736F
DC MOTOR DRIVER IC
The TA7736P is a 3 phase Bi−directional motor driver IC.
It designed for use VCR, 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
1.0 A.
l Few External Parts Required.
l Wide Operating Supply Voltage Range
: VCC (opr) (Min.) = 7~20 V
l Forward and Reverse Rotation is Controlled Simply by Means
of a CW / CCW Control Signal Fed Into 16PIN.
l High Sensitivity of Position Sensing Amplifier.
(VH = 10 mVp−p (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.)
Weight
DIP16−P−300−2.54A : 1.11g (Typ.)
HSOP16−P−300−1.00 : 0.50g (Typ.)
