Maxim Integrated Products Inc. (Sunnyvale, CA) announced its new MAX6710 quad-voltage monitor in a six-pin SOT23 package, which monitors voltages down to 0.622V. Various combinations of fixed and adjustable voltages meet a variety of low-voltage system requirements. For example, integrated reset timing is designed to monitor multi-voltage systems in telecommunications, networking gear, storage devices, high-end printers and computers.
The MAX6710 operates from 1V to 5.5V with the power derived from one of the monitored inputs to reduce the need for a separate Vcc pin (except MAX6710Q). The MAX6710 consumes 25µA of quiescent current, and is specified over the extended temperature range. When one of the four monitored voltages falls below its threshold, the open-drain reset output asserts and remains asserted for at least 140ms. The reset output is internally pulled up to Vcc to reduce the need for an external resistor, but can be overdriven to accommodate other logic devices.
There are 17 versions of the MAX6710 with different thresholds and supply tolerances to meet the requirements of various applications. Preset thresholds for monitoring 5V, 3.3V, 3V, 2.5V or 1.8V, as well as adjustable versions, accommodate most of today's standard logic devices. In lots of 2,500, prices start at $1.67.
