The MAX16070/MAX16071 flash-configurable system monitors supervise multiple system voltages. The MAX16070/MAX16071 can also accurately monitor (±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-ended analog-to-digital converter (ADC). Device configuration 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 programmable general-purpose inputs/outputs (GPIOs). GPIOs are flash configurable as dedicated fault outputs, as a watchdog input or output, or as a manual reset.
The MAX16070/MAX16071 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 MAX16070/MAX16071. The MAX16070/MAX16071 are available in a 40-pin, 6mm x 6mm, TQFN package. Both devices are fully specified from -40°C to +85°C.
