Description
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 programmable 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 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 MAX16065/MAX16066. The MAX16065 is available in a 48-pin, 7mm x 7mm, TQFN package, and the MAX16066 is available in a 40-pin, 6mm x 6mm, TQFN package. Both devices are fully specified from -40°C to +85°C.
