General Description
The MAX16031/MAX16032 EEPROM-configurable sys-
tem monitors feature an integrated 10-bit analog-to-
digital converter (ADC) designed to monitor voltages,
temperatures, and current in complex systems. These
EEPROM-configurable devices allow enormous flexibility
in selecting operating ranges, upper and lower limits,
fault output configuration, and operating modes with
the capability of storing these values within the device.
The MAX16031 monitors up to eight voltages, three
temperatures (one internal/two external remote temper-
ature diodes), and a single current. The MAX16032
monitors up to six voltages and two temperatures (one
internal/one remote temperature diode). Each of these
monitored parameters is muxed into the ADC and writ-
ten to its respective register that can be read back
through the SMBus and JTAG interface.
Measured values are compared to the user-config-
urable upper and lower limits. For voltage measure-
ments, there are two undervoltage and two overvoltage
limits. For current and temperature, there are two sets
of upper limits. Whenever the measured value is out-
side its limits, an alert signal is generated to notify the
processor. Independent outputs are available for over-
current, overtemperature, and undervoltage/overvolt-
age that are configured to assert on assigned
channels. There are also undedicated fault outputs that
are configured to offer a secondary limit for tempera-
ture, current, or voltage fault or provide a separate
overvoltage output.
During a major fault event, such as a system shutdown,
the MAX16031/MAX16032 automatically copy the inter-
nal ADC registers into the nonvolatile EEPROM registers
that then are read back for diagnostic purposes.
The MAX16031/MAX16032 offer additional GPIOs that
are used for voltage sequencing, additional fault out-
puts, a manual reset input, or read/write logic levels. A
separate current-sense amplifier with an independent
output allows for fast shutoff during overcurrent condi-
tions. The MAX16031/MAX16032 are available in a
7mm x 7mm TQFN package and are fully specified
from -40°C to +85°C.
