TA8435H Datasheet – Stepping Motor Driver IC
PWM CHOPPER TYPE BIPOLAR STEPPING MOTOR DRIVER
Package HZIP25-P type
TA8435H overview
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.
The TA8435H controls PWM to set the stepping motor winding current to a constant current. The device is a micro−step driver IC used to efficiently drive the stepping motor at low vibration
