Description

The UCD90160 is a 16-rail PMBus/I2C addressable power-supply sequencer and monitor. The device integrates a 12-bit ADC for monitoring up to 16 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 UCD90160 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. This PC-based graphical user interface (GUI) offers an intuitive interface for configuring, storing, and monitoring all system operating parameters.

Features

  • Monitor and sequence 16 voltage rails
    • All rails sampled every 400 µs
    • 12-bit ADC with 2.5-V, 0.5% internal VREF
    • Sequence based on time, rail and pin dependencies
    • Four programmable undervoltage and overvoltage thresholds per monitor
  • Nonvolatile error and peak-value logging per monitor (up to 12 fault detail entries)
  • Closed-loop margining for 10 rails
    • Margin output adjusts rail voltage to match user-defined margin thresholds
  • Programmable watchdog timer and system reset
  • Pin selected rail states for ACPI support
  • Flexible digital I/O configuration
  • Multiphase PWM clock generator
    • Clock frequencies from 15.259 kHz to 125 MHz
    • Capability to configure independent clock outputs for synchronizing switch-mode power supplies
  • JTAG and I2C/SMBus/PMBus™ interfaces
