Microprocessor Voltage Monitors
with Programmable Voltage Detection
________________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

o Improved 2nd Source for ICL8211/ICL8212
o Low-Power CMOS Design
o 5 μ A Quiescent Current
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

_______________Ordering Information
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.
