3. Current Feedback Circuit and Current Setting Circuit
(A/B unit (C/D unit is the same as A/B unit))
Function
The current setting circuit is used to set the reference voltage of the output current using the micro-step
current setting data input from the DATA pins.
The current feedback circuit is used to output to the output control circuit the relation between the set
current value and output current. This is done by comparing the reference voltage output to the current
setting circuit with the potential difference generated when current flows through the current sense
resistor connected between RS and VM.
The chopping waveform generator circuit to which CR is connected is used to generate clock used as
reference for the chopping frequency.
Note 1: RS COMP 1: Compares the set current with the output current and outputs a signal when the output current
reaches the set current.
Note 2: RS COMP 2: Compares the set current with the output current at the end of Fast mode during chopping.
Outputs a signal when the set current is below the output current.
