General Description

The UCD90124A 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.

Twenty-six GPIO pins can be used for power supply enables, power-on reset signals, external interrupts, cascading, or other system functions.

Key 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.
