A 33 kΩ resistance and a nearly peak
hold circuit for 0.22 µF capacitor are
connected to this pin for input signal
exist check at CS IN input pin. When
a signal is input at CS IN pin, a nearly
peak hold is executed at 2.1 V to 2.7
V, a comparison is made with the 1.4
V reference voltage, and input signal
exist is identified.
