3. Current feedback circuit and current setting circuit
Note 1: RS COMP 1: Compares the set current with the output current and outputs a signal when the output current
Note 2: RS COMP 2: Compares the set current with the output current at the end of Fast mode during chopping.
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 V
The chopping waveform generator circuit to which CR is connected is used to generate clock used as
reference for the chopping frequency.
(A/B unit (C/D unit is the same as A/B unit)
reaches the set current.
Outputs a signal when the set current is below the output current.
