GENERAL DESCRIPTION

The ADM1066 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 ADM1066 integrates a 12-bit ADC and six 8-bit

voltage output DACs. These circuits can be used to implement a

closed-loop margining system, which enables supply adjustment

by altering either the feedback node or reference of a dc/dc

converter using the DAC outputs.

User EEPROM: 256 bytes

Industry-standard 2-wire bus interface (SMBus)

Guaranteed PDO low with VH, VPn = 1.2 V
