10-Rail Sequencer and System Health Monitor With 10-Fan Control

Check for Samples: UCD90910

FEATURES

DESCRIPTION

The UCD90910 is a ten-rail I²C / PMBus addressable

power-supply sequencer and system-health

monitor. The device integrates a 12-bit ADC for

monitoring up to 13 power-supply voltage, current, or

temperature inputs.

•

Monitor and Sequence Ten Voltage Rails

–

All Rails Sampled Every 400 ms

12-Bit ADC With 2.5-V, 0.5% Internal V_REF

Sequence Based on Time, Rail and Pin

Dependencies

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

UCD90910 offers support for fan control, margining,

and general-purpose PWM functions.

–

Four Programmable Undervoltage and

Overvoltage Thresholds per Monitor

•

Fan Control and Monitoring

–

Supports Ten Fans With Five User-Defined

Speed-vs-Temperature Setpoints

Fan-control signals can be sent using PMBus

commands or generated from one of two built-in

fan-control algorithms. PWM outputs combined with

temperature and fan-speed measurements provide a

complete fan-control solution for up to ten

independent fans.

–

Supports Two-, Three-, and Four-Wire Fans

•

Nonvolatile Error and Peak-Value Logging per

Monitor (up to 12 Faults)

Closed-Loop Margining for Ten Rails

–

Margin Output Adjusts Rail Voltage to

Match User-Defined Margin Thresholds

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.
