    High impedance input to supply fault detector with thresholds between 0.573 V and 1.375 V
    General-purpose logic input
  • 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
  • Open collector with external pull-up
  • Push/pull output, driven to VDDCAP or VPn

Product Details

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.

The device also provides up to 10 programmable inputs for moni-toring undervoltage faults, overvoltage faults, or out-of-window faults on up to 10 supplies. In addition, 10 programmable outputs can be used as logic enables. Six of these programmable outputs can provide up to a 12 V output for driving the gate of an N-FET that can be placed in the path of a supply.

Applications

  • Central office systems
  • Servers/routers
  • Multivoltage system line cards
  • DSP/FPGA supply sequencing
  • In-circuit testing of margined supplies
  • Product Lifecycle icon-recommended Production
