Description for the UCD9090-Q1

The UCD9090-Q1 is a 10-rail PMBus and I2Caddressable power-supply sequencer and monitor. The device integrates a 12-bit ADC for monitoringup 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 thesepins offer PWM functionality. Using these pins, the UCD9090-Q1 offers support formargining, and general-purpose PWM functions.

Specific power states can be achieved using the pin-selected rail states feature. Thisfeature allows with the use of up to 3 GPIs to enable and disable any rail. This is useful forimplementing 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 providesdevice configuration. This PC-based user interface (UI) offers an intuitive interface forconfiguring, storing, and monitoring all system operating parameters.
