OPERATION – VOLTAGE DETECTOR
The CAT808 has an active low output that asserts
(pulls low) when the supply voltage drops below the
detection threshold voltage (V
DET
). The open-drain
output requires an external pull-up resistor between
the output pin and the supply voltage (as shown in
the typical application diagram). On power-up, ˉˉˉˉ
is held active low until the supply voltage (V
DD
) rises
above V
DET
. While V
DD
is above V
DET
, ˉˉˉˉ stays
high until V
DD
drops below V
DET
, then ˉˉˉˉ once
again goes low.
