Microprocessor Voltage Monitors

with Programmable Voltage Detection

MAX8211/MAX8212

General Description

Features

● μP Power-Fail Warning

The Maxim’s MAX8211 and MAX8212 are CMOS micro-

power voltage detectors that warn microprocessors (μPs)

of power failures. Each contains a comparator, a 1.15V

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.

● Improved 2nd Source for ICL8211/ICL8212

● Low-Power CMOS Design

● 5μA Quiescent Current

● On-Board Hysteresis Output

● ±40mV Threshold Accuracy (±3.5%)

● 2.0V to 16.5V Supply-Voltage Range

● Deﬁne Output Current Limit (MAX8211)

● High Output Current Capability (MAX8212)

The MAX8211 provides a 7mA current-limited output sink

whenever the voltage applied to the threshold pin is less

than the 1.15V internal reference. In the MAX8212, a

voltage greater than 1.15V 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

several performance advantages, including reduced sup-

ply current, a more tightly controlled bandgap reference,

and more available current from the hysteresis output.
