MAX8211CPA+

产品概述

The MAX8211CPA+ is a Microprocessor Voltage Monitor with programmable voltage detection. The MAX8211 is CMOS micropower voltage detectors that warn microprocessors (µPs) of power failures. Each contains a comparator, a 1.5V bandgap reference and an open-drain n-channel output driver. Two external resistors are used in conjunction with the internal reference to set the trip voltage to the desired level. A hysteresis output is also included, allowing the user to apply positive feedback for noise-free output switching. The MAX8211 provides a 7mA current-limited output sink whenever the voltage applied to the threshold pin is less than the 1.5V internal reference. The CMOS MAX8211 is plug-in replacements for the bipolar ICL8211 in applications where the maximum supply voltage is less than 16.5V. They offer several performance advantages, including reduced supply current, a more tightly controlled bandgap reference and more available current from the hysteresis output.
