12-Channel/8-Channel, Flash-Configurable System
Monitors with Nonvolatile Fault Registers
General Description
The MAX16070/MAX16071 flash-configurable sys-
tem monitors supervise multiple system voltages. The
MAX16070/MAX16071 can also accurately monitor
( Q 2.5%) one current channel using a dedicated high-
side current-sense amplifier. The MAX16070 monitors
up to twelve system voltages simultaneously, and the
MAX16071 monitors up to eight supply voltages. These
devices integrate a selectable differential or single-end-
ed analog-to-digital converter (ADC). Device configura-
tion information, including overvoltage and undervoltage
limits and timing settings are 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 read-back.
The internal 1% accurate 10-bit ADC measures each
input and compares the result to one overvoltage, one
undervoltage, and one early warning limit that can be
configured as either undervoltage or overvoltage. 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.
Because the MAX16070/MAX16071 support a power-
supply voltage of up to 14V, they can be powered
directly from the 12V intermediate bus in many systems.
The MAX16070/MAX16071 include eight/six program-
mable general-purpose inputs/outputs (GPIOs). GPIOs
