ADM1266 Datasheet Cascadable Super Sequencer

Manufacturer: Analog Devices

Overview: Data Sheet ADM1266 Cascadable Super Sequencer with Margin Control and Fault.

General Description

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 proprietary 2-wire interface (interdevice bus).

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.

Key Features

  • Complete supervisory and sequencing solution for up to 17 supplies.
  • 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.
  • 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 su.
