ADM1062
Supply margining can be performed with a minimum of external
components. The margining loop can be used for in-circuit
testing of a board during production (for example, to verify
board functionality at −5% of nominal supplies), or it can be
used dynamically to accurately control the output voltage of
a dc-to-dc converter.
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 also 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.

Temperature measurement is possible with the ADM1062. The
device contains one internal temperature sensor and a differen-
tial input for a remote thermal diode. Both 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 ADM1062 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.
