TA8529F

The TA8529F is a stepping motor driver IC which operates based on bipolar transistors.

Features of the TA8529F are:(1)two low-staturation-voltage bridge drivers:saturation voltage <0.95V(IQ=400mA);(2)1-phase excitation,2-phase excitation,1/2-phase excitation enabled by four-port inputs(pin 11 open);(3)2-phase excitation enabled by two-port inputs(pins 8,9,11 grounded);(4)built-in standby function;(5)built-in rush-current protector circuit for when switching exitation current;(6)standard 20-pin PFP;(7)GND pin=heat sink.

The maximum ratings of the TA8529F can be summarized as:(1):the characteristic is power supply voltage,the symbol is VCC1,the rating is 7.0,the unit is V;(2):the characteristic is power supply voltage,the symbol is VCC2,the rating is 17.0,the unit is V;(3):the characteristic is output current,the symbol is IO(MAX),the rating is ±500,the unit is mA;(4):the characteristic is input voltage,the symbol is VIN,the rating is VCC1,the unit is V;(5):the characteristic is power dissipation,the symbol is PD,the rating is 1.0,the unit is W;(6):the characteristic is operating temperature,the symbol is Topr,the rating is -30 to 75,the unit is ;(7):the characteristic is storage temperature,the symbol is Tstg,the rating is -55 to 150.
