TA8423P/F
TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA8423P,TA8423F
3 PHASE Bi−DIRECTIONAL HALL MOTOR DRIVER
The TA8423P, TA8423F are 3 phase Bi−Directional Hall Motor
Driver IC designed for VCR (Capstan, head and reel), ADP, Tape
Deck, FDD and other Output Driver for 3 phase bipolar Hall
motors.
FEATURES
l Few external parts required
l Wide operating supply voltage range
: VCC (opr) = 7~17 V
l Forward rotation, reverse rotation and stop are controlled by 1
terminal signal control and easy to interface with CPU.
l High sensitivity of the position sensing circuit.
(Hall sensor input) : VH = 20 mVp−p (Typ.)
l Large output current : IO (MAX.) = 1.2 A
l Protect diodes equipped for all inputs
l Recommend to use TOSHIBA Ga−As Hall sensor “THS100
series”
l Built−in internal reference
l Built−in thermal shut down circuit
Weight
DIP16−P−300−2.54A : 1.11g (Typ.)
HSOP16−P−300−1.00 : 0.50g (Typ.)

Note:
“1” of the Hall Sensor input means that voltage above +20 mV is applied to the positive side of each Hall
Sensor from the negative side and “0” means that voltage above +20 mV is applied to the negative side from
the positive side.
In this case, needless to say, DC potential must be within the specified common mode voltage range of Hall
Sensor input.
Further, “H”, “M” and “L” of output mean VCC − VSAT1 = 1 / 2 VCC and VSAT2, respectively.
