2.Standby function
Standby is ON when Pin1 is set to "L". By applying a 5 V to the standby pin, transistor Q1 will be turned ON to
provide a constant current (I) for driving other parts of the circuit. The RC is to create a TIME CONSTANT for the
standby pulse during charging and discharging.
Threshold voltage (at Pin1) :

3.Muting
By controlling Pin2 from "H" to "L", the mute function is set from ON to OFF. When Pin2 is floating, DC

≈
2.8 V. The RC is to create a TIME CONSTANT for the mute pulse during charging and
discharging.
