FEATURES  
DESCRIPTION

•
Monitor and Sequence 12 Voltage Rails  
The UCD90124 is a 12-rail PMBus/I2C addressable  
power-supply sequencer and system-health  
–
–
–
All Rails Sampled Every 400 μs  
12-bit ADC With 2.5-V, 0.5% Internal VREF  
monitor. The device integrates a 12-bit ADC for  
monitoring up to 13 power-supply voltage, current, or  
temperature 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 UCD90124 offers  
Sequence Based on Time, Rail and Pin  
Dependencies  
–
Four Programmable Undervoltage and  
Overvoltage Thresholds per Monitor  
•
Fan Control and Monitoring  
–
Supports Four Fans With Five User-Defined  
Speed-vs-Temperature Setpoints  
support  
for  
fan  
control,  
margining,  
and  
general-purpose PWM functions.  
–
Supports Two-, Three-, and Four-Wire Fans  
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 four  
independent fans.  
•
•
Nonvolatile Error and Peak-Value Logging per  
Monitor (up to 12 Faults)  
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.
