Description



Features:

Complete supervisory and sequencing solution for up to 10 supplies
10 supply fault detectors enable supervision of supplies to better than 1% accuracy
5 selectable input attenuators allow supervision:
    Supplies up to 14.4 V on VH
    Supplies up to 6 V on VP14
5 dual-function inputs, VX15:
    High impedance input to supply fault detector with thresholds between 0.573 V and 1.375 V
    General-purpose logic input
10 programmable output drivers (PDO110):
    Open collector with external pull-up
    Push/pull output, driven to VDDCAP or VPn
    Open collector with weak pull-up to VDDCAP or VPn
    Internally charge-pumped high drive for use with external N-FET (PDO16 only)
Sequencing engine (SE) implements state machine control of PDO outputs:
    State changes conditional on input events
    Enables complex control of boards
    Power-up and power-down sequence control
    Fault event handling
    Interrupt generation on warnings
    Watchdog function can be integrated in SE
    Program software control of sequencing through SMBus
12-bit ADC for readback of all supervised voltages
2 auxiliary (single-ended) ADC inputs
Reference input, REFIN, has 2 input options:
    Driven directly from 2.048V (±0.25%) REFOUT pin
    More accurate external reference for improved ADC performance
Device powered by the highest of VP14, VH for improved redundancy
User EEPROM: 256 bytes
Industry-standard 2-wire bus interface (SMBus)
Guaranteed PDO low with VH, VPn = 1.2 V
40-lead 6 mm * 6 mm LFCSP and 48-lead 7 mm * 7 mm TQFP packages

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.
