12-Channel/8-Channel EEPROM-Programmable

System Managers with Nonvolatile Fault Registers

7/MX16049A

General Description

Features

The MAX16047A/MAX16049A EEPROM-configurable sys-

tem managers monitor, sequence, and track multiple sys-

tem voltages. The MAX16047A manages up to twelve

system voltages simultaneously, and the MAX16049A

manages up to eight supply voltages. These devices inte-

grate an analog-to-digital converter (ADC) for monitoring

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 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

(MAX16047A) or up to eight (MAX16049A) 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.

Watchdog Timer Function

Manual Reset

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 +125°C Operating Temperature Range

The MAX16047A/MAX16049A include six programma-

ble 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 MAX16047A/MAX16049A feature two methods of

fault management for recording information during criti-

cal 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.

Ordering Information

An I C/SMBus™-compatible or a JTAG serial interface

configures the MAX16047A/MAX16049A. These devices

are offered in a 56-pin, 8mm x 8mm TQFN package and

are fully specified from -40°C to +125°C.
