Application Circuits
Stepping motor driver application circuit example
The setting conditions for the above circuit diagram example are as follows :
2-phase excitation (MD1/DC11 = Low, MD2/DC12 = Low)
Auto recovery-type output short-circuit protection function (EMM = Low)
Reset function fixed to normal operation (RST = High)
Chopping frequency : 37kHz (RCHOP = 43k)
