UCD90120A - 12-Rail Power-Supply Sequencer/Monitor

Datasheet Summary

Description

The UCD90120A is a 12-rail PMBus/I2C addressable power-supply sequencer and monitor.

The device integrates a 12-bit ADC for monitoring up to 12 power-supply voltage inputs.

Features

  • 1 Monitor and Sequence 12 Voltage Rails.
  • All Rails Sampled Every 400 μs.
  • 12-bit ADC With 2.5-V, 0.5% Internal VREF.
  • Sequence Based on Time, Rail and Pin Dependencies.
  • Four Programmable Undervoltage and Overvoltage Thresholds per Monitor.
  • Nonvolatile Error and Peak-Value Logging per Monitor (up to 12 Fault Detail Entries).
  • Closed-Loop Margining for 10 Rails.
  • Margin Output Adjusts Rail Voltage to Match User-Defined Margin Thre.
