MAX16055HAUB+

The MAX16055HAUB+ is an ultra small precision hex voltage microprocessor (μP) supervisor in 10 pin µMAX package. This supervisory circuit monitors up to six system supply voltages and asserts a single reset when any one supply voltage drops below its preset threshold. It significantly reduces system size and component count while improving reliability compared to multiple ICs or discrete components. A variety of factory trimmed threshold voltages are available to accommodate different supply voltages and tolerance with minimal external components. A single active-low, open drain output asserts when any monitored input falls below its associated threshold. The reset output features a weak internal pull-up (typically 70μA) to supply input IN1 and it remains low for reset timeout period (140ms minimum) after all voltages rise above the selected thresholds. The reset output remains valid as long as either IN1 or IN2 input voltage is above 1V.

• Supply voltage range from 1V to 5.5V
• Automotive temperature range from -40°C to 125°C
• Precision factory set reset threshold options 3.3V, 3V, 2.5V, 1.8V, 1.5V, 1.2V, 1.1V, 1V and 0.9V
• Adjustable voltage threshold monitors down to 0.5V with 1.5% accuracy
• Manual reset input
• Tolerance select (5% / 10%) input
• Immune to short supply transients
• Threshold voltage of 3.08V (3.3V, TOL = GND) and reset timeout period of 200ms
