Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

Pin No. Mnemonic Description
1
ENIN, ENIN
Enable Input. Controls the status of the enable output. Active high for ADM1085/ADM1086. Active low for
ADM1087.
2 GND Ground.
3 V
IN
Input for the Monitored Voltage Signal. Can be biased via a voltage divider resistor network to customize the
effective input threshold. Can precisely monitor an analog power supply output signal and detect when it has
powered up. The voltage applied at this pin is compared with a 0.6 V on-chip reference. With this reference,
digital signals with various logic level thresholds can also be detected.
4
ENOUT, ENOUT
Enable Output. Asserted when the voltage at V
IN
is above V
TH_RISING
and the time delay has elapsed, provided
that the enable input is asserted. Active high for the ADM1085/ADM1086. Active low for the ADM1087.
5 CEXT
External Capacitor Pin. The capacitance on this pin determines the time delay on the enable output. The delay
is seen only when the voltage at V
IN
rises past V
TH_RISING
, and not when it falls below V
TH_FALLING
.
