General Description
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.
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
(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.
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).
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.
An I2C/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.
