CMOS Output Type
OUT pin is connected to the drain
of Nch Tr. and Pch Tr. in this IC.
Nch Open Drain Output Type
OUT pin is connected to the drain
of Nch Tr. in this IC. (OUT pin should be
pulled up to V
DD
or an external voltage
level.)

Operating Diagram
In the above diagram,
!
Output Voltage becomes equal to supply voltage (Nch Open Drain Output Type; equal to pull-up Voltage).
"
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 GND level.
#
When Supply Voltage is lower than minimum operating voltage, Output of transistor is indefinite, therefore Out-
put is also indefinite.
$
Output Voltage is equal to GND level.
%
When Supply voltage is higher than Released Voltage (Point B), 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).
* There is no hysteresis range between Detector threshold and Released Voltage.
