The UCD9090 is a 10-rail PMBus/I2C addressable power-supply sequencer and monitor. The device integrates a 12-bit ADC for monitoring up to 10 power-supply voltage inputs. Twenty-three GPIO pins can be used for power supply enables, power-on reset signals, external interrupts, cascading, or other system functions. Ten of these pins offer PWM functionality. Us.
•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 thresholds
• Programmable watchdog timer and system reset
• Flexible digital I/O configuration
• Pin-selected rail states
• Cascading multiple devices
• Multi-phase PWM.
