6-Channel, Flash-Configurable System Manager
with Nonvolatile Fault Registers
General Description
The MAX16067 flash-configurable system manager
monitors and sequences multiple system voltages. The
MAX16067 manages up to six system voltages simulta-
neously. The MAX16067 integrates an analog-to-digital
converter (ADC) and configurable outputs for sequenc-
ing power supplies. Device configuration information,
including overvoltage and undervoltage limits, time
delay settings, and the sequencing order is stored in
nonvolatile flash memory. During a fault condition, fault
flags and channel voltages 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 MAX16067 supports a power-supply voltage of up to
14V and can be powered directly from the 12V interme-
diate bus in many systems.
The integrated sequencer provides precise control over
the power-up and power-down order of up to six power
supplies. Three outputs (EN_OUT1 to EN_OUT3) are
configurable with charge-pump outputs to directly drive
external n-channel MOSFETs.
The MAX16067 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 MAX16067 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
MAX16067. The MAX16067 is available in a 32-pin, 5mm
x 5mm, TQFN package and is fully specified over the
