of multiple power rails
3 Description
The UCD9090-Q1 is a 10-rail PMBus and I2C
addressable power-supply sequencer and
monitor. The device integrates a 12-bit ADC for
monitoring up to 10 power-supply voltage
inputs. Twenty-three GPIO pins can be used for
power supply enables, power-on reset signals,
external interrupts, cascading, or other system
functions. Ten of these pins offer PWM
functionality. Using these pins, the UCD9090-Q1
offers support for margining, and general-purpose
PWM functions.
1
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
provides device configuration. This PC-based user
interface (UI) offers an intuitive interface for
configuring, storing, and monitoring all system
operating parameters.
