Three ICs support IoT’s emerging applications
The MAX6078A voltage reference IC, the MAX16155 nanoPower supervisor and the MAX16160 voltage monitor and reset IC contribute to performance capabilities for cloud infrastructure, IoT, intelligence-at-the-edge, on-device AI, as well as smart and emerging applications in consumer, communications, industrial and medical markets, says Maxim Integrated.
All three can be used by designers to reduce power consumption and solution size, while improving measurement accuracy, claims the company.
The trio have been added to the Essential Analog portfolio of high-performance, single-function analogue ICs.
The MAX6078A precision voltage reference IC delivers industrial accuracy on a tight battery power budget, explains Maxim. It has ±0.04 per cent initial accuracy, which is claimed to be 20 per cent more accurate than similar competitive devices. It has 15microA quiescent current in readiness for precision measurements on battery-powered and energy-harvesting systems. It operates at 6.6 times less current than the closest competitive parts, continues Maxim. It measures 1.458 x 1.288mm, which makes it 58 per cent smaller than competing solutions, adds the company.
The MAX16155 nanoPower supervisor consumes just 400nA typical, or only four per cent of the supply current that competitive solutions require, according to Maxim, for reliable system protection for virtually no power. It can be used to ensure portable, low-power devices operate safely in the event of a power failure or code error by monitoring a system rail for under-voltage fault and keeping the system in reset when it senses the fault along with a watchdog timer. The IC is supplied in a six-pin SOT23 package.
The four-channel MAX16160 voltage monitor and reset IC is believed to be the only four-channel voltage monitor and reset IC that asserts reset low without requiring VCC rail if any of the rails is above 1V. It is claimed to have the industry’s most reliable start-up and continuous operation of multi-supply systems by asserting output low. No-power-power-up eliminates unknown system states and assists design engineers to accurately sequence their power rail start-up. With a voltage monitoring accuracy of ±one per cent for all inputs, it is up to 50 per cent more accurate than competitive offerings (commonly ±1.50 per cent for all inputs), claims Maxim. It is supplied in a six-bump WLP, measuring 1.408 x 0.848mm. According to Maxim, this is 85 per cent smaller than the closest competitor.
All three devices are available now. An evaluation kit, for the MAX6078A, the MAX6078EVKIT# evaluation kit, is also available.
