ICL7665CSA+

Supervisors Overview

The ICL7665CSA+ is a dual-channel voltage monitor integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within an input supply voltage range of 1.6 V to 16 V and consumes a typical quiescent current of 15 µA. The device provides two independent monitored inputs with selectable threshold voltages, including overvoltage thresholds at 1.4 V and 1.45 V, and undervoltage thresholds at 1.15 V and 1.2 V. It features an accuracy of 2% and offers active high, active low, or open drain output configurations. The component supports battery backup switching and lacks manual reset or watchdog timer functions.
