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.
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.
