• Systems Requiring Sequencing and Monitoring of

Multiple Power Rails

Description

The UCD90320U device is a 32-rail PMBus™

addressable power sequencer and system manager

in a compact 0.8-mm pitch BGA package. ULA mold

compound is adopted to reduce the soft errors

caused by alpha particles. The device scans the user

configuration SRAM to detect single event upset

(SEU). Both features provide higher reliability for the

applications.

The 24 integrated ADC channels (AMONx) monitor

the power supply voltage, current, and temperature.

Of the 84 GPIO pins, 8 can be used as digital

monitors (DMONx), 32 to enable the power supply

(ENx), 24 for margining (MARx), 16 for logical GPO,

and 32 GPIs for cascading, and system function.

The 32 ENx pins and the 16 LGPOx pins can be

configured to be active driven or open drain outputs.

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 up to 128 voltage rails through one

SYNC_CLK pin connection.
