Device Undervoltage/Early Warning Limit configuration information, including overvoltage and S Nonvolatile Fault Event Logger undervoltage limits, timing settings, and the sequenc- ing order is stored in nonvolatile flash memory. During a S Power-Up and Power-Down Sequencing fault condition, fault flags and channel voltages can be Capability automatically stored in the nonvolatile flash memory for S Independent Secondary Sequence Block later read-back. S 12/8 Outputs for Sequencing/Power-Good The internal 1% accurate 10-bit ADC measures each Indicators input and compares the result to one overvoltage, one S Two Programmable Fault Outputs and One Reset undervoltage, and one early warning limit that can be Output configured as either undervoltage or overvoltage. A fault signal asserts when a monitored voltage falls outside the S Eight General-Purpose Inputs/Outputs set limits. Up to three independent fault output signals Configurable as: are configurable to assert under various fault conditions. Dedicated Fault Outputs Because the MAX16065/MAX16066 support a power- Watchdog Timer Function supply voltage of up to 14V, they can be powered Manual Reset directly from the 12V intermediate bus in many systems.

GPIO s Telecom Equipment (Base Stations, Access) are flash configurable as dedicated fault outputs, as a Storage/Raid Systems watchdog input or output, or as a manual reset. Servers The MAX16065/MAX16066 feature nonvolatile fault memory for recording information during system shut- Ordering Information down events. The fault logger records a failure in the internal flash and sets a lock bit protecting the stored PART TEMP RANGE PIN-PACKAGE fault data from accidental erasure. An SMBus or a JTAG MAX16065ETM+ -40NC to +85NC 48 TQFN-EP* serial interface configures the MAX16065/MAX16066. MAX16066ETL+ 40 TQFN-EP* -40NC to +85NC The MAX16065 is available in a 48-pin, 7mm x 7mm, TQFN package, and the MAX16066 is available in a +Denotes a lead(Pb)-free/RoHS-compliant package. 40-pin, 6mm x 6mm, TQFN package.
