GENERAL DESCRIPTION

The ADM1064 Super Sequencer® 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 that can be used to accurately read back up to 12 separate voltages.

FEATURES

Complete supervisory and sequencing solution for up to

10 supplies

10 supply fault detectors enable supervision of supplies to

<0.5 accuracy at all voltages at 25°C

<1.0 accuracy across all voltages and temperatures

5 selectable input attenuators allow supervision of supplies to

14.4 V on VH

6 V on VP1 to VP4 (VPx)

5 dual-function inputs, VX1 to VX5 (VXx)

High impedance input to supply fault detector with

thresholds between 0.573 V and 1.375 V

General-purpose logic input

10 programmable driver outputs, PDO1 to PDO10 (PDOx)

Push/pull output, driven to VDDCAP or VPx

Open collector with weak pull-up to VDDCAP or VPx

Internally charge-pumped high drive for use with external

N-FET (PDO1 to PDO6 only)

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
