ADM1266

FEATURES

GENERAL DESCRIPTION

Complete supervisory and sequencing solution for up to

17 supplies

The ADM1266 Super Sequencer® is a configurable supervisory/

sequencing device that offers a single-chip solution for supply

monitoring and sequencing in systems with up to 17 supplies.

For systems with more supplies (up to 257), the operation of up

to 16 ADM1266 devices can be synchronized through a proprie-

tary 2-wire interface (interdevice bus).

Expandable to 257 supplies with additional ADM1266 ICs

connected to the 2-wire interdevice bus

Fully programmable sequencing engine

17 supply fault detectors enable real time supervision of

supplies

The sequencing engine (SE) monitors the supply fault detectors

(SFDs), programmable driver input/outputs (PDIOs), general-

purpose inputs/outputs (GPIOs), and timers, and controls the

PDIOs and GPIOs to sequence the supplies up and down as

required. The logical core of the device is an ARM® Cortex-M3

microcontroller. The firmware is supplied by Analog Devices,

Inc., and all configuration is performed through an intuitive

graphic user interface (GUI).

0.4 V to 15 V on VH1 to VH4 (VHx)

0.4 V to 5 V on VP1 to VP13 (VPx)

Device powered by the higher of VH1 and VH2 inputs for

improved operating redundancy

12-bit ADC for readback of all supervised voltages

Black box nonvolatile fault recording

16 PDIOs

9 GPIOs

Additionally, the ADM1266 integrates an analog-to-digital

converter (ADC) and voltage output digital-to-analog converters

(DACs) that can be used to adjust either the feedback node or

reference of a dc-to-dc converter to implement a closed-loop,

autonomous, margining system.

9 voltage output 8-bit DACs allow voltage margining

adjustment via dc-to-dc converter trim/feedback node

Main and backup memory

Industry standard PMBus interface compliant

Available in a 9 mm × 9 mm, 64-lead package

A block of nonvolatile EEPROM is available to record voltage,

time, and fault information when instructed to by the sequencing

engine configuration.
