Texas Instruments' model UCD9090ARGZR (click to buy now) is a power monitoring chip and is a 10-rail PMBus/I2C addressable power supply sequencer and monitor. The UCD9090ARGZR integrates a 12-bit ADC for monitoring up to 10 supply voltage inputs. There are 23 general-purpose input and output (GPIO) pins, which can be used for power enable, power-on reset signal, external interrupt, cascading or other system functions. 10 of the GPIO pins provide PWM functionality. Utilizing these pins, the UCD9090ARGZR supports margining as well as general-purpose PWM functionality.
Specific power states can be achieved using the pin-select voltage rail state feature, which allows up to 3 GPIs to be used to enable and disable any voltage rail. Enforces system low-power modes and Advanced Configuration and Power Interface (ACPI) for hardware devices.
Functional features of UCD9090ARGZR
