UCD9090ARGZT

支持 ACPI 的 10 轨电源序列发生器和监视器 48-VQFN -40 to 125

The UCD9090A is a 10-rail PMBus/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 UCD9090A 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 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.
