CMOS Output Type
OUT pin is connected to the drain
of Nch Tr. and Pch Tr. in this IC.
Nch Open Drain Output Type: I
OUT pin is connected to the drain
of Nch Tr. in this IC. (OUT pin should be
pulled up to V

Operation Diagram
In the above diagram,
!
Output Voltage becomes equal to GND level.

When Supply Voltage is down to the detector threshold level (Point A), Vref
≥
V
DD
×
Rb/(Ra+Rb) is true. Then,
Output of the comparator is reversed, thus output voltage becomes equal to Supply Voltage (Nch Open Drain
Output type; equal to pull-up Voltage).
#
When Supply Voltage is lower than minimum operating voltage, Output of transistor is indefinite, therefore Out-
put is also indefinite.(Nch Open Drain Output type; Output voltage level is equal to pull-up voltage.)
$
Output Voltage is equal to Supply Voltage. (Nch Open Drain Output type; equal to pull-up Voltage.)

When Supply voltage is higher than Released Voltage (Point B), Vref
≤

DD
×
Rb/(Ra+Rb) is true. Then Output of
the comparator is reversed, thus Output Voltage becomes equal to GND level after the output delay time.
* There is no hysteresis range between Detector threshold and Released Voltage.
