Overview
19-5003; Rev 0; 10/09 12-Channel/8-Channel, Flash-Configurable System Monitors with Nonvolatile Fault Registers General Description The MAX16070/MAX16071 flash-configurable system monitors supervise multiple system voltages.
The MAX16070/MAX16071 can also accurately monitor (Q2.
5%) one current channel using a dedicated highside 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 powersupply 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 www.

com 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, ...
