SLVSAN8 –JANUARY 2012  
12-Rail Power Supply Sequencer and Monitor with ACPI Support and Fan Control  
Check for Samples: UCD90124A  
1
FEATURES  
DESCRIPTION  
The UCD90124A is a 12-rail PMBus/I2C addressable  
power-supply sequencer and monitor. 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 UCD90124A offers

•
•
Nonvolatile Error and Peak-Value Logging per  
Monitor (up to 12 Fault Detail Entries)  
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.  
Closed-Loop Margining for 10 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.
