12-Channel/8-Channel, Flash-Configurable System
Managers with Nonvolatile Fault Registers
General Description
The MAX16065/MAX16066 flash-configurable system
managers monitor and sequence multiple system volt-
ages. The MAX16065/MAX16066 can also accurately
monitor (±2.5%) one current channel using a dedicated
high-side current-sense amplifier. The MAX16065 man-
ages up to twelve system voltages simultaneously, and
the MAX16066 manages up to eight supply voltages.
These devices integrate a selectable differential or sin-
gle-ended analog-to-digital converter (ADC) and con-
figurable outputs for sequencing power supplies. Device
configuration information, including overvoltage and
undervoltage limits, timing settings, and the sequenc-
ing 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 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 MAX16065/MAX16066 support a power-
supply voltage of up to 14V, they can be powered
directly from the 12V intermediate bus in many systems.
The integrated sequencer provides precise control over
the power-up and power-down order of up to twelve
(MAX16065) or up to eight (MAX16066) power supplies.
Eight outputs (EN_OUT1–EN_OUT8) are configurable
with charge-pump outputs to directly drive external
n-channel MOSFETs.
The MAX16065/MAX16066 include eight/six programma-
ble general-purpose inputs/outputs (GPIO_s). GPIO_s
are flash configurable as dedicated fault outputs, as a
watchdog input or output, or as a manual reset.
The MAX16065/MAX16066 feature nonvolatile fault mem-
ory for recording information during system shutdown
events. The fault logger records a failure in the internal
