OPERATION – VOLTAGE DETECTOR
The CAT808 has an active low output that asserts
(pulls low) when the supply voltage drops below the
detection threshold voltage (VDET). 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, OUT
is held active low until the supply voltage (VDD) rises
above VDET. While VDD is above VDET, OUT
stays
high until VDD drops below VDET, then OUT
once
again goes low.
