DESCRIPTION

Operating supply D.C. voltage rectified from ringing signal.

Oscillator External Trigger/Inhibit pin (must beconnected through

a current limiting resistor, which is used to program the slope of

supply current vs voltage.)

Low Frequency Time Constant Adjustment pins fL is controlled

externally by R2 and C2

fL = 1/1.289R2C2

Ground

High Frequency Time Constant Adjustment Pins fH1 and fH2 are

controlled externally by R3 and C3.

fH1=1/1.504R3C3, fH2 = 1/1.203R3C3
