TA8435H

The TA8435H is PMW chopper type sinusoidal micro step bipolar stepping motor driver.Sinusoidal micro step operation is accomplished only a clock signal inputting by means of built-in hard wave.

Features of the TA8435H are:(1)1 chip bipolar sinusoidal micro step stepping micro step stepping motor driver;(2)output current up to 1.5A (AVE.) and 2.5A (PEAK);(3)PWM chopper type;(4)structured by high voltage Bi-CMOS process technology;(5)forward and reverse rotation are available;(6)2,1-2,W1-2,2W1-2 phase 1 or 2 clock drives are selectable;(7)package : HZIP25-P;(8)input pull-up resistor equipped with RESET terminal : R=100k (Typ.);(9)output montor available with MO. IO(MO) =±2mA (MAX.);(10)reset and enable are available with RESET and ENABLE.
