The UCD90240 is a 24-rail PMBus addressable power sequencer and system manager in a compact 9-mm × 9-mm BGA package.

The device provides 24 analog monitor (MON) pins to monitor power-supply voltage, current, or temperature with two 12-bit ADC engines, 24 dedicated enable (EN) pins to control power rail on/off, 24 dedicated margin pins for closed-loop margining, 12 Logic GPO (LGPO) pins to support flexible Boolean logic and state machine functions, and 24 GPIO pins which can be configured as GPI, GPO, System Reset, cascading fault pins, and Watchdog I/O, and so forth.

The 24 EN pins and the 12 LGPO 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 and preserves the status of all rails and I/O pins when the first fault occurs.

The cascading feature offers convenient ways to manage up to 96 voltage rails through one SYNC_CLK pin connection. The Fault Pin feature coordinates among cascaded devices to take synchronized fault responses.

The Pin-Selected Rail States feature uses up to three 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.

The TI Fusion Digital Power™ designer software is an intuitive PC-based graphical user interface (GUI) that can configure, store, and monitor all system operating parameters.
