Additional InformationMaxim’s MAX8211 is a CMOS micropower voltage detector 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 a plug-in replacement 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.
