· (Rb+Rc)/(Ra+Rb+Rc)at Point A (Detected Voltage –V
DET
), the output of Compara-
tor is reversed, so that Output Voltage becomes GND. Discharging is performed from C
D
pin connected to External Capacitor. No delay time is
generated.
Step 3. Output Voltage becomes indefinite when Power Source Voltage (V
DD
) is smaller than Minimum Operating Voltage. When the output is pulled-
up,V

is output.
Step 4. Output Voltage becomes equal to GND.
