Description

1

ENIN, ENIN

Enable Input. Controls the status of the enable output. Active high for ADM1085/ADM1086. Active low for

ADM1087/ADM1088.

2

GND

Ground.

3

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.

that the enable input is asserted. Active high for the ADM1085/ADM1086. Active low for the

ADM1087/ADM1088.

5

CEXT

External Capacitor Pin. The capacitance on this pin determines the time delay on the enable output. The delay
