UCD9090 Product details

Description

The UCD9090 is a 10-rail PMBus/I2C addressable power-supply sequencer and monitor.

Features

1 Monitor and sequence 10 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 30 fault detail entries).
Closed-loop margining for 10 rails.
Margin output adjusts rail voltage to match user-defined margin thre.
