OPERATION
FIG. 1 Block Diagram
Operation Diagram
Step 1. Output Voltage is equal to Power Source Voltage (V
DD
).
Step 2. When Input Voltage to Comparator reaches the state of Vref
≥
V
DD
·(Rb+Rc)/(Ra+Rb+Rc)at Point A (Detected Voltage –V
DET
), the output of Com-
parator is reserved, so that Output Voltage becomes GND.
Step 3. In the case of CMOS Output, Output Voltage becomes unstable when Supply Voltage (V
DD
) is smaller than Minimum Operating Voltage. In the
case of Nch Open Drain Output, a pulled-up voltage is output.
Step 4. Output Voltage becomes equal to GND.
Step 5. When Input Voltage to Comparator reaches the state of Vref
≤
V
DD
· (Rb)/(Ra+ Rb) at Point B (Released Voltage +V
DET
), the output of Comparator is reversed,
so that Output Voltage becomes equal to Supply Voltage (V
DD
).
