CMOS Micropower Over/Under Voltage
Detector
The ICL7665S Super CMOS Micropower Over/Under
Voltage Detector contains two low power, individually
programmable Voltage detectors on a single CMOS chip.
Requiring typically 3µA for operation, the device is intended
for battery-operated systems and instruments which require
high or low voltage warnings, settable trip points, or fault
monitoring and correction. The trip points and hysteresis of
the two voltage detectors are individually programmed via
external resistors. An internal bandgap-type reference
provides an accurate threshold voltage while operating from
any supply in the 1.6V to 16V range.
The ICL7665S, Super Programmable Over/Under Voltage
Detector is a direct replacement for the industry standard
ICL7665B offering
wider
operating voltage and temperature
ranges,
improved
threshold accuracy (ICL7665SA), and
temperature coefficient, and
guaranteed
maximum supply
current. All improvements are highlighted in the electrical
characteristics section.
All critical parameters are
guaranteed over the entire commercial and industrial
temperature ranges.
