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.
