Features, Applications

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 Applications 4 Rail Profiles for Adaptive Voltage Identification (AVID) Voltage Regulator High-Accuracy Closed-Loop Margining Active Trim Function Improves Rail Output Voltage Accuracy Advanced Nonvolatile Event Logging To Assist System Debugging ­ Single-Event Fault Log (100 entries) ­ Peak Value Log ­ Black Box Fault Log to Save Status of All Rails and I/O Pins at the First Fault Easily Cascade to 4 Power Sequencers and Take Coordinated Fault Responses Programmable Watchdog Timer and System Reset Pin-Selected Rail State PMBusTM 1.2 Compliant

Nonvolatile event logging preserves fault events after power dropout. Black box fault log feature preserves the status for all rails and I/O pins when the first fault occurs. The cascading feature offers convenient ways to manage to 128 voltage rails through one SYNC_CLK pin connection. Fault pin feature coordinates among cascaded devices to take synchronized fault responses. The pin-selected rail states feature employs to 3 GPIs to control up to eight user-defined power states. These states can implement system low-power modes as outlined in the Advanced Configuration and Power Interface (ACPI) specification. Device Information(1)

The UCD90320 device a 32-rail PMBusTM 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. Eighty-four GPIO pins can be used for 8 digital monitor (DMONx), 32 power supply enable (ENx), 24 margining (MARx), 16 Logical GPO, 32 GPI, cascading, and system function. The 32 ENx pins and the 16 LGPOx pins can be configured to be active driven or open drain outputs.
