UCD90320 - Power Sequencer and System Manager

General Description

The UCD90320 device is a 32-rail PMBus™ addressable power sequencer and system manager in a compact 0.8-mm pitch BGA package.

The 24 integrated ADC channels (AMONx) monitor the power supply voltage, current, and temperature.

Key Features

  • 1 Sequence, Monitor, and Margin 24 Voltage Rails Plus 8 Digital Rails.
  • Monitor and Respond to OV, UV, OC, UC, Temperature, Time-Out, and GPI-Triggered Faults.
  • Flexible Sequence-On and Off Dependencies, Delay Time, Boolean Logic, and GPIO Configuration to Support Complex Sequencing.
