ADM1062-69 FAMILY DESCRIPTION
These devices also provide up to ten programmable inputs for
monitoring Under, Over, or out-of-window faults on up to ten
supplies. In addition, up to ten programmable outputs are
provided. These can be used as logic enables. Six of them can
also provide up to a +12V output for driving the gate of an N-
Channel FET which may be placed in the path of a supply.
The logical core of the device is a Sequencing Engine. This is a
state machine based construction, providing up to 63 different
states. This enables very flexible sequencing of the outputs,
based on the condition of the inputs.
In addition to these functions, the ADM1062/3/4/6/9 integrate a
12-bit ADC. This allows read-back of the voltage on up to 12
rails. An extra level of UV or OV monitoring can also be
provided with the ADC.
The ADM1062/6/7/9 also have 8-bit voltage output DACs.
These circuits can be used to implement an open-loop
margining system that enables supply adjustment by altering
either the feedback node or reference of a dc/dc converter using
the DAC outputs. For parts with ADC also present a more
comprehensive closed-loop margining circuit can be
implemented.
Temperature measurement is possible with the ADM1062/3.
The ADM1062 contains one internal temperature sensor and a
differential input for a remote thermal diode. The ADM1063
contains an additional differential input for a second remote
thermal diode. These are measured using the 12- bit ADC.
The device is controlled via configuration data that can be
programmed into an EEPROM. The whole configuration can
be programmed using an intuitive GUI-based software package
provided by ADI.
