ICL7665CSA Description

Short technical summary and product information.

The ICL7665CSA from Intersil is a monolithic, low-power CMOS supervisory circuit designed to monitor microprocessor voltage levels. It provides warnings for both overvoltage and undervoltage conditions, making it suitable for battery-powered systems and power-supply fault monitoring.

Key features include a wide supply voltage range of 1.6V to 16V and an exceptionally low operating current of only 3µA. The trip points and hysteresis for its two voltage detectors are externally programmable via resistors, allowing monitoring of voltages from 1.3V up to several hundred volts. The ICL7665A variant offers improved performance with a 2% threshold accuracy.

This device is ideal for applications such as low-battery detection, power-fail and brownout detection, and battery backup switching. It is available in an 8-SOIC package and is designed for surface mount applications.

The ICL7665CSA integrates a precision internal reference, dual comparators, and on-board hysteresis outputs, reducing component count and board space in many circuits.
