Microprocessor Voltage Monitor with
Dual Over/Undervoltage Detection
_______________General Description
The ICL7665 warns microprocessors (碌Ps) of overvolt-
age and undervoltage conditions. It draws a typical
operating current of only 3碌A(chǔ). The trip points and hys-
teresis of the two voltage detectors are individually pro-
grammed via external resistors to any voltage greater
than 1.3V. The ICL7665 will operate from any supply
voltage in the 1.6V to 16V range, while monitoring volt-
ages from 1.3V to several hundred volts. The Maxim
ICL7665A is an improved version with a 2%-accurate
V
SET1
threshold and guaranteed performance over
temperature.
The 3碌A(chǔ) quiescent current of the ICL7665 makes it
ideal for voltage monitoring in battery-powered sys-
tems. In both battery- and line-powered systems, the
unique combination of a reference, two comparators,
and hysteresis outputs reduces the size and compo-
nent count of many circuits.
