GENERAL DESCRIPTION
The ADM1063 is a configurable supervisory/sequencing device
that offers a single-chip solution for supply monitoring and
sequencing in multiple supply systems. In addition to these
functions, the ADM1063 integrates a 12-bit ADC that can be
used to accurately read back up to 12 separate voltages.
The device also provides up to 10 programmable inputs for
monitoring undervoltage faults, overvoltage faults, or out-of-
window faults on up to 10 supplies. In addition, 10 programmable
outputs can be used as logic enables. Six of these programmable
outputs can provide up to a 12 V output for driving the gate of
an N-FET that can be placed in the path of a supply.
For more information about the ADM1063 register map,
refer to the AN-698 Application Note.

ADM1063
Data Sheet
Temperature measurement is possible with the ADM1063. The
device contains one internal temperature sensor and two pairs
of differential inputs for remote thermal diodes. These are
measured by the 12-bit ADC.
The logical core of the device is a sequencing engine. This state-
machine-based construction provides up to 63 different states.
This design enables very flexible sequencing of the outputs
based on the condition of the inputs.
The device is controlled via configuration data that can be
programmed into an EEPROM. The entire configuration can
be programmed using an intuitive GUI-based software package
provided by Analog Devices, Inc.

Description
External Temperature Sensor 1 Cathode Connection.
External Temperature Sensor 1 Anode Connection.
Device Supply Voltage. Linearly regulated from the highest of the VPx, VH pins to a typical of
4.75 V. Note that the capacitor must be connected between this pin and GND. A 10 μF
capacitor is recommended for this purpose.
Supply Ground.
Exposed Pad. The LFCSP has an exposed pad on the bottom. This pad is a no connect (NC). If
possible, this pad should be soldered to the board for improved mechanical stability.
1 In a typical application, all ground pins are connected together.
2 N/A is not applicable.
