POWER - 12-/8-channel system monitors integrate current monitoring and nonvolatile fault registers

Sunnyvale, Calif. - The MAX16070 and MAX16071 from Maxim Integrated Products are flash-configurable system monitors that supervise 12/8 voltages plus one current. Designed to simplify power-management schemes in multivoltage systems, these devices feature an integrated current monitor, nonvolatile fault registers, and an easy-to-use graphical configuration tool. The MAX16070/MAX16071 provide 1% accurate voltage monitoring for networking, telecom, server/storage, and other complex systems where high reliability is critical.

The 2.5% accurate current monitor eliminates the need for an external current-sense amplifier, thus simplifying design, saving board space, and reducing costs. When two inputs are configured as a differential pair, the devices can simultaneously monitor both the current and voltage in the power-supply rail.

The new monitors integrate an ADC and nonvolatile fault registers to store and read back fault data, enabling users either to save information about a monitored input that caused the problem or write all of the measured values into flash memory. Users can then read back fault conditions to help debug design. If a system or board is returned to the factory, the manufacturer will now have useful fault data to analyze and determine what caused the failure.

The easy-to-use graphical configuration tool eliminates the need for programming of complex devices like programmable logic devices (CPLDs) and microprocessors. The tool allows designers to quickly generate fault data for analysis or test different configurations with an I2C or JTAG interface.

The MAX16070/MAX16071 have a wide 2.8V to 14V operating voltage range, and allow operation directly from an intermediate bus voltage. The devices are fully specified over the -40 degrees Celsius to +85 degrees Celsius extended temperature range.

The MAX16070/MAX16071 are available in a 6mm x 6mm, 40-pin TQFN package. Prices start at $5.65 (1000-up, FOB USA). Samples are available now.
