MAX16046/MAX16048

12-Channel/8-Channel EEPROM-Programmable

System Managers with Nonvolatile Fault Registers

General Description

The MAX16046/MAX16048 EEPROM-configurable sys-

tem managers monitor, sequence, track, and margin

multiple system voltages. The MAX16046 manages

up to twelve system voltages simultaneously, and the

MAX16048 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 stor-

ing 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 out-

puts to directly drive MOSFETs without closed-loop tracking.

The MAX16046/MAX16048 include twelve/eight integrated

8-bit DAC outputs for margining power supplies when con-

nected 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 as 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.

An I

C or a JTAG serial interface configures the MAX16046/

MAX16048. 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 specified from -40°C to +85°C.
