Overview
TA8435H/HQ TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA8435H/HQ PWM CHOPPER-TYPE BIPOLAR STEPPING MOTOR DRIVER.
The TA8435H/HQ is a PWM chopper-type sinusoidal micro-step bipolar stepping motor driver.
Sinusoidal micro-step operation is achieved using only a clock signal input by means of built-in hardware.
FEATURES z Single-chip bipolar sinusoidal micro-step stepping motor driver z Output current up to 1.
5 A (AVE.
) and 2.
5 A (PEAK) z PWM chopper-type z Structured by high voltage Bi-CMOS process technology z Forward and reverse rotation are available z 2-, 1-2-, W1-2-, and 2W1-2-phase modes, and one- or two-clock drives can be selected.
z Package: HZIP25-P z Input pull-up resistor equipped with RESET pin: R = 100 kΩ (typ.
