_______________General Description

____________________________Features

µP Over/Undervoltage Warning

The ICL7665 warns microprocessors (µPs) of overvolt-

age and undervoltage conditions. It draws a typical

operating current of only 3µA. 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

temperature.

The 3µA 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.
