The MAX16046/MAX16048 EEPROM-configurable system

managers monitor, sequence, track, and margin multiple

system voltages. The MAX16046 manages up to twelve

system voltages simultaneously, and the MAX16048 man-

ages 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 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 readback following failures.

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.

The integrated sequencer/tracker allows precise control

over the power-up and power-down order of up to twelve

(MAX16046) or up to eight (MAX16048) 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.

The MAX16046/MAX16048 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.

The MAX16046/MAX16048 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.

The MAX16046/MAX16048 feature two methods of fault

management for recording information during system

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.

56-pin 8mm x 8mm TQFN package and are fully speci-

fied from -40°C to +85°C.
