12-Channel/8-Channel EEPROM-Programmable  
System Managers with Nonvolatile Fault Registers  
/MX16048A  
General Description  
Features  
o Operates from 3V to 14V  
The MAX16046A/MAX16048A EEPROM-configurable sys-  
tem managers monitor, sequence, track, and margin mul-  
tiple system voltages. The MAX16046A manages up to  
twelve system voltages simultaneously, and the  
MAX16048A manages up to eight supply voltages. These  
devices integrate an analog-to-digital converter (ADC) for  
monitoring supply voltages, digital-to-analog converters  
(DAC) for adjusting supply voltages, and configurable out-  
puts 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 readback following failures.  
o 1% Accurate 10-Bit ADC Monitors 12/8 Inputs  
o 12/8 Monitored Inputs with 1 Overvoltage/  
1 Undervoltage/1 Selectable Limit  
o 12/8 8-Bit DAC Outputs for Margining or Voltage  
Adjustments  
o Nonvolatile Fault Event Logger  
o Power-Up and Power-Down Sequencing  
Capability  
o 12/8 Outputs for Sequencing/Power-Good  
Indicators  
o Closed-Loop Tracking for Up to Four Channels  
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 Two Programmable Fault Outputs and One Reset  
Output  
o Six General-Purpose Input/Outputs Configurable as:  
Dedicated Fault Output  
Watchdog Timer Function  
Manual Reset  
Margin Enable Input  
The integrated sequencer/tracker allows precise control  
over the power-up and power-down order of up to twelve  
(MAX16046A) or up to eight (MAX16048A) power sup-  
plies. 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.  
2
o I C/SMBus-Compatible and JTAG Interface  
o EEPROM-Configurable Time Delays, Thresholds,  
and DAC Outputs  
o 100 Bytes of Internal User EEPROM  
o -40°C to +125°C Operating Temperature Range  
The MAX16046A/MAX16048A include twelve/eight inte-  
grated 8-bit DAC outputs for margining power supplies  
when connected to the trim input of a point-of-load  
(POL) module.  
Applications  
Servers  
The MAX16046A/MAX16048A include six programmable  
general-purpose inputs/outputs (GPIOs). GPIOs are  
EEPROM configurable as dedicated fault outputs, as a  
watchdog input or output (WDI/WDO), as a manual reset  
(MR), or for margin control inputs.  
Workstations  
Storage Systems  
Networking/Telecom  
The MAX16046A/MAX16048A feature two methods of  
fault management for recording information during sys-  
tem shutdown 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 MAX16046A/MAX16048A. These devices  
are offered in a 56-pin, 8mm x 8mm TQFN package or a  
64-pin, 10mm x 10mm TQFP package and are fully speci-  
fied from -40°C to +125°C.
