UCD9081 - 8-Channel Power-Supply Sequencer/Monitor

Datasheet Summary

Description

The UCD9081 power-supply sequencer controls the enable sequence of up to eight independent voltage rails and provides four general-purpose digital outputs (GPO).

The device operates from a 3.3-V supply, provides 3.2-mV resolution of voltage rails, and requires no external memory or clock.

Features

  • 1 Single Supply Voltage: 3.3 V.
  • Low Power Consumption: 3-mA Nominal Supply Current.
  • Sequences and Monitors Eight Voltage Rails.
  • Rail Voltages Sampled With 3.2-mV Resolution.
  • Internal or External Voltage Reference.
  • Four Configurable Digital Outputs for Power-On- Reset and Other Functions.
  • Configurable Digital Output Polarity.
  • Flexible Rail Sequencing Based on Timeline (ms), Parent Rail Regulation Window, or Parent Rail Achiev.
