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.
Weight: 9.86 g (typ.)
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.
TA8435HQ:
