Product Overview

The UCD90120ARGCT is a 12-rail PMBus/I²C addressable Power-supply Sequencer and Monitor with ACPI support. The device integrates a 12-bit ADC for monitoring up to 12 power-supply voltage inputs. Twenty-six GPIO pins can be used for power supply enables, power-on reset signals, external interrupts, cascading or other system functions. Twelve of these pins offer PWM functionality. Using these pins, the UCD90120A 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 TI Fusion Digital Power™ designer software is provided for device configuration.
  • All rails sampled every 400µs
  • 12-bit ADC with 2.5V, 0.5% internal VREF
  • Sequence based on time, rail and pin dependencies
  • Four programmable under-voltage and over-voltage thresholds per monitor
  • Non-volatile error and peak-value logging per monitor (up to 12 fault detail entries)
  • Closed-loop margining for 10 rails
  • Programmable watchdog timer and system reset
  • Flexible digital I/O configuration
  • Clock frequencies from 15.259kHz to 125MHz
  • Capability to configure independent clock outputs for synchronizing switch-mode power supplies
  • JTAG and I²C/SMBus/PMBus™ interfaces
  • Green product and no Sb/Br
