Maxim Intros MAX6709 and MAX6714 Voltage Monitors

Maxim Integrated Products Inc. (Sunnyvale, CA) announced its new MAX6709 and MAX6714 quad-voltage monitors, which provide fixed thresholds to monitor 1.8V to 5V supplies and adjustable thresholds for monitoring voltages down to 0.62V. Available in 10-pin µMAX packages, both devices are designed to monitor low-voltage systems in telecommunications and networking equipment, storage devices, printers, and PCs.

When any of the four monitored voltages for the MAX6709 falls below its threshold, its respective active-low, power-good output asserts and stays asserted until the monitored voltage exceeds the threshold. For the MAX6714, if the Vcc falls below its threshold, the reset output asserts and remains asserted for at least 140ms after the Vcc exceeds its threshold. The IC also has three power-fail comparators to monitor three independent voltages down to 0.62V.

Both devices have active-low, open-drain outputs with 10µA internal pullup to Vcc. The internally trimmed thresholds and weak internal pullups minimize the need for external components. Pricing for both devices starts at $2.50 for quantities of 1,000 units and up.
