• DC motor driver application circuit example
The setting conditions for the above circuit diagram example are as follows :
The current limit value is as follows :
•
•
•
•
Auto recovery-type output short-circuit protection function (EMM = Low)
Output enable function fixed to output ON state (OE = High)
Current limit reference voltage setting = 100% (ATT1 = Low, ATT2 = Low)
Chopping frequency : 37kHz (RCHOP = 43kΩ)
Ilimit = (VREF/3) /0.25Ω
