ICL7665SACBA-T

Supervisors Overview

The ICL7665SACBA-T is a CMOS micropower over/under voltage detector manufactured by Renesas Electronics Corporation. It features two independently programmable voltage detectors with adjustable trip points, allowing for precise threshold setting via external resistors. The device operates from a supply voltage range of 1.6 V to 16 V and consumes typically 3 µA of operating current. It provides accurate threshold voltage detection without requiring manual reset or featuring a watchdog timer. The component is housed in an 8-SOIC surface-mount package and is designed for applications requiring reliable power supervision.

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm RoHS compliance status as datasheets may vary by revision. Check for end-of-life notices or obsolescence warnings from Renesas. Ensure the SOIC-8 package dimensions match your PCB footprint requirements. Validate that the adjustable threshold functionality meets your circuit design needs.

Supervisors Selection Notes

Select this component when adjustable voltage thresholds are required for dual-channel monitoring. Consider the 3 µA quiescent current for battery-sensitive designs. Verify the 1.6 V to 16 V input range covers your system's operational voltages. Compare against fixed-threshold alternatives if programmability is unnecessary. Ensure the SOIC-8 package fits your assembly constraints.

Supervisors Part Context

The ICL7665S belongs to the Super Programmable Over/Under Voltage Detector family from Intersil/Renesas. It complements variants like the ICL7665SA which offers improved accuracy and temperature coefficients. The series is part of Renesas's PMIC portfolio for power management supervision. It serves as a critical component for ensuring system stability during power fluctuations.

Supervisors Replacement Considerations

The ICL7665SCBAZA is listed as a parameter equivalent alternative. Verify pin compatibility and electrical specifications before substitution. Check for any differences in package tolerance or thermal characteristics. Confirm availability and lead times for both components.
