ICL7665BCPA

The ICL7665BCPA from Intersil is a versatile dual over/undervoltage monitor IC. It is engineered to provide accurate monitoring of two voltage levels, making it suitable for power supply supervision and protection circuits.

This IC operates with a supply voltage ranging from 1.6V to 16V and boasts an exceptionally low quiescent current of approximately 3µA. It incorporates two comparators, a precise voltage reference, and internal hysteresis on its outputs. The internal hysteresis is crucial for preventing rapid output chattering when the monitored voltage hovers around the threshold.

The ICL7665BCPA is available in a standard DIP-8 package, facilitating through-hole mounting in various electronic designs. Its functionality includes detecting voltage drops below a set threshold and rises above another set threshold, triggering distinct outputs (OUT1 and OUT2) accordingly. This makes it an ideal component for safeguarding sensitive electronic circuits from power supply anomalies.

Applications for the ICL7665BCPA include monitoring power supply rails in battery-powered devices, embedded systems, and other electronics where reliable voltage supervision is critical. Its low power consumption and dual-channel monitoring capability offer efficient and effective protection.
