Step 1. Output Voltage is equal to Pull-up Voltage.
Step 2. When Input Voltage (VSEN2) reaches the state of Vref
≥ VSEN2 (Rb+Rc)/(Ra+Rb+Rc)at Point A (Detected Voltage –VDET), the output of Compara-
tor is reversed, so that Output Voltage becomes GND. Discharging is performed from CD pin connected to External Capacitor. No delay time is
generated.
Step 3. Output Voltage becomes indefinite when Power Source Voltage (VDD) is smaller than Minimum Operating Voltage. When the output is pulled-
up,VDD is output.
Step 4. Output Voltage becomes equal to GND.
Step 5. When Input Voltage (VSEN2) reaches the state of Vref
≤VSEN2 Rb/(Ra + Rb) at Point B (Released Voltage +VDET), the output of Comparator is reversed, and
the External Capacitor is charged through CD pin,so that Output Voltage becomes equal to Pulled-up Voltage after a delay timeTD (= 0.69
× 106 × CD).
Step of Operation
The following descriptions deal with VDD pin and VSEN2 pin as connected each other, but Detector 2 can be detect-
ed the different voltage from VDD through VSEN2 pin.
