Ordering Information/Selector Guide
General Description
The MAX16068 flash-configurable system manager
monitors and manages up to six system voltages
simultaneously. The MAX16068 integrates an analog-
to-digital converter (ADC). Device configuration infor-
mation, including overvoltage and undervoltage limits,
time delay settings is stored in nonvolatile flash memory.
During a fault condition, fault flags and channel volt-
ages can be automatically stored in the nonvolatile flash
memory for later readback.
The internal 1% accurate, 10-bit ADC measures each
input and compares the result to one overvoltage and
one undervoltage limit. A fault signal asserts when a
monitored voltage falls outside the set limits.
The MAX16068 supports a power-supply voltage of up to
14V and can be powered directly from the 12V interme-
diate bus in many systems.
The MAX16068 includes six programmable general-
purpose inputs/outputs (GPIOs). GPIOs are flash con-
figurable as a fault output, as a watchdog input or output,
or as a manual reset.
The MAX16068 features nonvolatile fault memory for
recording information during system shutdown events.
The fault logger records a failure in the internal flash
and sets a lock bit protecting the stored fault data from
accidental erasure.
An SMBus™ or a JTAG serial interface configures the
MAX16068. The MAX16068 is available in a 28-pin, 5mm
x 5mm, TQFN package and is fully specified over the
-40NC to +85NC extended temperature range.
