Description

The UCD90120A is a 12-rail PMBus/I2C addressable

power-supply sequencer and monitor. The device

integrates a 12-bit ADC for monitoring up to 12

power-supply voltage inputs. Twenty-six GPIO pins

can be used for power supply enables, power-on

reset signals, external interrupts, cascading, or other

system functions. Twelve of these pins offer PWM

functionality. Using these pins, the UCD90120A offers

support for margining, and general-purpose PWM

functions.

Specific power states can be achieved using the Pin-

Selected Rail States feature. This feature allows with

the use of up to 3 GPIs to enable and disable any

rail. This is useful for implementing system low-power

modes and the Advanced Configuration and Power

Interface (ACPI) specification that is used for hardware devices.

The TI Fusion Digital Power™ designer software is

provided for device configuration. This PC-based

graphical user interface (GUI) offers an intuitive

interface for configuring, storing, and monitoring all

system operating parameters.
