GENERAL DESCRIPTION

The ADM1064 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 ADM1064 integrates a 12-bit ADC which can be

used to accurately read back up to 12 separate voltages.

Industry-standard 2-wire bus interface (SMBus)

Guaranteed PDO low with VH, VPn = 1.2 V
