3 Description
The UCD90240 is a 24-rail PMBus addressable
power sequencer and system manager in a compact
9-mm Γ— 9-mm BGA package.
1
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
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 Powerβ„’ designer software is
an intuitive PC-based graphical user interface (GUI)
that can configure, store, and monitor all system
operating parameters.
