Product Information

19-5040; Rev 0; 10/09 6-Channel, Flash-Configurable System Manager with Nonvolatile Fault Registers General Description The MAX16068 flash-configurable system manager monitors and manages up to six system voltages simultaneously. The MAX16068 integrates an analogto-digital converter (ADC). Device configuration information, including overvoltage and undervoltage limits, time delay settings 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 MAX16068 supports a power-supply voltage of up to 14V and can be powered directly from the 12V intermediate bus in many systems. The MAX16068 includes six programmable generalpurpose inputs/outputs (GPIOs). GPIOs are flash configurable as a fault output, as a watchdog input or output, or as a manual reset. The MAX16068 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 MAX16068. www.DataSheet4U.com The MAX16068 is available in a 28-pin, 5mm x 5mm, TQFN package and is fully specified over the -40NC to +85NC extended temperature range.
