TA8435HQ

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.) z Output monitor available with MO IO ( MO ) = ±2 mA (MAX.) z Equipped with RESET and ENABLE pins.
