ICL7665SCBAZA

Supervisors Overview

The ICL7665SCBAZA is a CMOS micropower supervisory circuit manufactured by Renesas Electronics Corporation. It integrates two individually programmable voltage detectors for over/under voltage monitoring within a single chip. The device operates with a supply voltage range of 1.6 V to 16 V and consumes typically 10 µA of current. It features open-drain outputs and lacks manual reset or watchdog timer functions. The component is housed in an 8-SOIC surface-mount package and supports battery backup switching capabilities.

Supervisors Feature Summary

• Integrates two low-power, individually programmable voltage detectors on a single CMOS chip
• Provides open-drain output configuration for flexible interface compatibility
• Supports battery backup switching functionality for data retention
• Operates without manual reset inputs or integrated watchdog timers

Supervisors Applications

• Battery-operated portable instrumentation systems
• Memory power back-up circuits
• Charging systems requiring voltage supervision

Supervisors Procurement Notes

Verify the obsolete status of this component through official Renesas channels before procurement planning. Confirm availability of parameter-equivalent alternatives such as the ICL7665SACBAZ if inventory acquisition is required. Ensure compliance with RoHS3 specifications and check for any product change notices affecting assembly sites or labeling prior to integration into new designs.

Supervisors Selection Notes

Select this component when designing systems requiring dual-channel voltage supervision with minimal quiescent current consumption. The wide operating voltage range up to 16 V accommodates various power rails. Consider the absence of manual reset and watchdog features during system architecture design. Verify that the open-drain output type aligns with the target logic levels and pull-up requirements of the monitored circuitry.
