TA8423P

The TA8423P is a kind of 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.

The features of TA8423P can be summarized as (1)few external parts required; (2)wide operating supply voltage range: VCC (opr) = 7~17V; (3)Forward rotation, reverse rotation and stop are controlled by 1 terminal signal control and easy to interface with CPU; (4)high sensitivity of the position sensing circuit (Hall sensor input): VH =20mVp-p(typ); (5)large output current : lO(MAX)=1.2A; (6)protect diodes equipped for all inputs; (7)recommend to use TOSHIBA Ga-As Hall sensor "THS100 series"; (8)built-in internal reference; (9)built-in thermal shut down circuit.

The absolute maximum ratings of TA8423P are (1)supply voltage VCC: 18V; (2)output current IO: 1.2A; (3)hall sensor input voltage VH: 400mVp-p; (4)power dissipation PD: 1.2W(no heat sink); (5)operating temperature Topr: -30~75°C; (6)storage temperature Tstg: -55~150°C:
