MAX16047/MAX16049

12-Channel/8-Channel EEPROM-Programmable

System Managers with Nonvolatile Fault Registers

General Description

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.

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

(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.

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).

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 con-

figures 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.
