ICL7665SIBAZA

Supervisors Overview

The ICL7665SIBAZA is a CMOS micropower supervisory circuit manufactured by Intersil (Renesas). It integrates two individually programmable voltage detectors on a single chip, designed for battery-operated systems. The device operates within a supply voltage range of 1.8 V to 16 V and features an open-drain output type. It supports adjustable threshold voltages for over/under detection without requiring manual reset or watchdog timers. The component is housed in an 8-SOIC package and maintains low power consumption with typical operating currents around 3 μA.

Supervisors Procurement Notes

Verify the specific suffix 'IBA' against official Renesas documentation to confirm pinout and electrical characteristics, as suffixes often denote package variations or temperature ranges. Ensure compatibility with existing PCB footprints and design specifications before procurement. Cross-reference datasheet revisions to confirm current manufacturing status and availability constraints.

Supervisors Selection Notes

Select this component when dual-channel voltage monitoring is required with minimal quiescent current. The adjustable threshold capability allows customization for specific system voltage requirements. Consider the 8-SOIC package dimensions for layout constraints. Verify that the open-drain output aligns with the downstream logic interface requirements of the target application.
