UCD9090ARGZT  Description


The UCD9090A is a 10-track PMBus/I2C addressable power sequencer and monitor. The device integrates a 12-bit ADC to monitor up to 10 power supply voltage inputs. 23 GPIO pins can be used for power-on, power-on reset signals, external interrupts, cascading or other system functions. Ten of the pins provide pulse width modulation. With these pins, UCD9090A supports margin adjustment and regular PWM functions. By using the track state function selected by the pin, a specific power state can be achieved. This feature allows you to enable and disable any track using up to 3 GPI. This is very useful for implementing the low power mode of the system and the advanced configuration and power interface (ACPI) specification of hardware devices. 0ATTI Fusion digital power designer software is used for device configuration. This PC-based graphical user interface (GUI) provides an intuitive interface for configuring, storing and monitoring all system operating parameters
