12-Channel/8-Channel EEPROM-Programmable  
System Managers with Nonvolatile Fault Registers  
7/MAX16049  
General Description  
Features  
The MAX16047/MAX16049 EEPROM-configurable system  
managers monitor, sequence, and track multiple system  
voltages. The MAX16047 manages up to twelve system  
voltages simultaneously, and the MAX16049 manages up  
to eight supply voltages. These devices integrate an ana-  
log-to-digital converter (ADC) for monitoring supply volt-  
ages, and configurable outputs for sequencing and  
tracking supplies (during power-up and power-down).  
Nonvolatile EEPROM registers are configurable for storing  
upper and lower voltage limits, setting timing and  
sequencing requirements, and for storing critical fault  
data for read back following failures.  
o Operates from 3V to 14V  
o 1% Accurate 10-Bit ADC Monitors 12/8 Inputs  
o 12/8 Monitored Inputs with One Overvoltage/  
One Undervoltage/One Selectable Limit  
o Nonvolatile Fault Event Logger  
o Power-Up and Power-Down Sequencing  
Capability  
o 12/8 Outputs for Sequencing/Power-Good  
Indicators  
An internal 1% accurate 10-bit ADC measures each input  
and compares the result to one upper, one lower, and  
one selectable upper or lower limit. A fault signal asserts  
when a monitored voltage falls outside the set limits. Up  
to three independent fault output signals are configurable  
to assert under various fault conditions.  
o Closed-Loop Tracking for Up to Four Channels  
o Two Programmable Fault Outputs and One Reset  
Output  
o Six General-Purpose Input/Outputs Configurable as:  
Dedicated Fault Output  
The integrated sequencer/tracker allows precise control  
over the power-up and power-down order of up to twelve  
(MAX16047) or up to eight (MAX16049) power supplies.  
Four channels (EN_OUT1–EN_OUT4) support closed-  
loop tracking using external series MOSFETs. Six outputs  
(EN_OUT1–EN_OUT6) are configurable with charge-  
pump outputs to directly drive MOSFETs without closed-  
loop tracking.  
Watchdog Timer Function  
Manual Reset  
2
o I C/SMBus-Compatible and JTAG Interface  
o EEPROM-Configurable Time Delays and  
Thresholds  
o 100 Bytes of Internal User EEPROM  
o 56-Pin (8mm x 8mm) TQFN Package  
o -40°C to +85°C Operating Temperature Range  
The MAX16047/MAX16049 include six programmable  
general-purpose inputs/outputs (GPIOs). In addition to  
serving as EEPROM-configurable I/O pins, the GPIOs  
are also configurable as dedicated fault outputs, as a  
watchdog input or output (WDI/WDO), or as a manual  
reset (MR).  
Applications  
Servers  
Workstations  
The MAX16047/MAX16049 feature two methods of fault  
management for recording information during critical  
fault events. The fault logger records a failure in the  
internal EEPROM and sets a lock bit protecting the  
stored fault data from accidental erasure.

An I C/SMBus™-compatible or a JTAG serial interface  
configures the MAX16047/MAX16049. These devices are  
offered in a 56-pin 8mm x 8mm TQFN package and are  
fully specified from -40°C to +85°C.
