ICL7665SCBAZ

Supervisors Overview

The ICL7665SCBAZ is a dual-channel CMOS supervisory circuit manufactured by Renesas Electronics. It functions as a voltage detector with adjustable threshold voltages, monitoring two independent input lines. The device features an open-drain output type and lacks manual reset or watchdog timer capabilities. It operates within a supply voltage range of 1.8 V to 16 V and supports battery backup switching for memory retention during power loss. The component is housed in an 8-SOIC surface-mount package and is designed for low-power applications requiring precise voltage supervision.

Supervisors Feature Summary

• Dual-channel voltage monitoring with adjustable threshold detection
• Open-drain output configuration for flexible logic interfacing
• Battery backup switching capability to preserve data integrity
• CMOS technology ensuring low quiescent current consumption

Supervisors Applications

• Portable instrumentation systems requiring voltage supervision
• Memory power backup circuits for data retention
• Battery-operated devices needing under-voltage detection
• Charging systems with multi-rail monitoring requirements

Supervisors Procurement Notes

Verify the specific suffix 'SCBAZ' against official Renesas documentation to confirm the exact package variant and temperature rating. Confirm RoHS compliance status and lead times through authorized distributors, as this part may be subject to limited availability or end-of-life notices. Ensure the selected variant matches the required SOIC-8 footprint and electrical specifications for the target design.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring with adjustable thresholds is required in a compact surface-mount package. Consider the open-drain output compatibility with system logic levels and the absence of manual reset functionality. Evaluate the operating temperature range and supply voltage limits against application constraints. Verify that the lack of a watchdog timer aligns with system safety requirements.

Supervisors Part Context

The ICL7665 series belongs to Renesas' portfolio of micro-power voltage supervisors designed for portable and battery-powered electronics. These devices provide reliable supervision for multiple voltage rails without requiring external components. The SCBAZ variant specifically denotes the SOIC-8 surface-mount package option within this family, offering space-efficient integration for modern circuit boards.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include ICL7665SACBAZ and ICL7665SACBAZA. Verify pinout compatibility and electrical parameter equivalence before substitution. Check manufacturer announcements for any obsolescence notices or recommended new parts for the ICL7665SCBAZ.
