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

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operationofthe
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

NOTES:

1. θJA is measured with the component mounted on an evaluation PC board in free air.

2. Due to the SCR structure inherent in the CMOS process used to fabricate these devices, connecting any terminal to voltages greater than (V+
+0.3V) or less than (GND - 0.3V) may cause destructive device latchup. For these reasons, it is recommended that no inputs from external
sources not operating from the same power supply be applied to the device before its supply is established, and that in multiple supply systems,
the supply to the ICL7665S be turned on first. If this is not possible, current into inputs and/or outputs must be limited to ±0.5mA and voltages
must not exceed those defined above.
