ICL7665S

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 3

µA 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.
