ICL7665BCSA

Supervisors Overview

The ICL7665BCSA is a dual-channel power supply supervisor manufactured by Analog Devices Inc./Maxim Integrated. It monitors two independent voltage inputs to detect overvoltage and undervoltage conditions. The device features adjustable threshold voltages set via external resistors, utilizing an internal bandgap reference for accuracy across the operating range. It provides open-drain or open-collector outputs with active-high or active-low logic options. Designed for surface-mount applications, it operates within a temperature range of 0°C to +70°C.
