1 pcs : UCD9090ARGZR - Supervisory Circuits 10-Rail Power Supply Sequencer and Monitor With ACPI Support 48-VQFN -40 to 125

UCD9090A Power Supply Sequencer Texas Instruments UCD9090A Power Supply Sequencer is a 10-rail PMBus/I2C addressable power-supply sequencer and monitor. The device integrates a 12-bit ADC for monitoring up to ten 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 Texas Instruments 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 the use of up to three GPIs to enable and disable any rail. This feature is useful for implementing system low-power modes and the Advanced Configuration and Power Interface (ACPI) specification used for hardware devices.
