Microprocessor Voltage Monitors

with Programmable Voltage Detection

MAX8211/MAX8212

________________General Description

Maxim’s MAX8211 and MAX8212 are 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. In the MAX8212, a voltage

greater than 1.5V at the threshold pin turns the output

stage on (no current limit).

The CMOS MAX8211/MAX8212 are plug-in replacements

for the bipolar ICL8211/ICL8212 in applications where the

maximum supply voltage is less than 16.5V. They offer sev-

eral performance advantages, including reduced supply

current, a more tightly controlled bandgap reference, and

more available current from the hysteresis output.
