CR Circuit Constants
OSC circuit oscillation waveform
The OSC circuit generates the chopping reference signal by charging and discharging the external capacitor Cosc
through current supplied from the external resistor Rosc in the OSC block.
Voltages E1 and E2 in the diagram are set by dividing the VDD by approximately 3/5 (E1) and 2/5 (E2).
The actual current chopping time is 1/8 the CR frequency.
[Important: Setting the cr circuit constants]
The CR oscillation waveform is converted in the IC to the CLK waveform (CR-CLK signal) and used for control.
If the CR waveform discharge time is set outside the range shown below, the operation of the IC is not guaranteed.
Be sure to set the CR waveform discharge time within the following range.
600 ns > t (CR discharge) > 400 ns
