Description
The THB***4AH is
aPWM
chopper-typesinusoidalmicro-stepbipolarstepping
motor driver
IC.(textile
machine,instruments,bridle machine,engraver machine,atomizing
machine,coiling mahine,dispenser machine ect step
motors.)
It supports 8 kind of
excitation modes and forward/reverse mode and is capable of
low-vibration, high-performance drive of *-phase
bipolar typestepping motors using only a clock
signal.
Features
