∗1 The VDD typical voltage setting is noted as 12.0V in the above table.
∗2 Connect the resistor and capacitor to the Cext/Rext pin as shown in the figure below.
The Cext/Rext value differs according to the rising time of the panel supply voltage.
∗3 For the VDDG, VSSG output setting, connect an external smoothing capacitor and a voltage stabilizing
Zener diode as shown in the figure below.
