ICL7665SCBAZ-T

Supervisors Overview

The ICL7665SCBAZ-T is a supervisory circuit manufactured by Renesas Electronics Corporation, designed for monitoring voltage levels in electronic systems. It features two monitored inputs with adjustable threshold voltages and an open-drain output type. The device operates within a supply voltage range of 1.8 V to 16 V and supports a manual reset function. It is housed in an 8-SOIC surface-mount package and is rated for operation at temperatures up to +85°C. This component belongs to the ICL7665S series of voltage detectors.

Supervisors Feature Summary

• Dual-channel voltage monitoring capability with adjustable trip points
• Open-drain output configuration for flexible interface integration
• Supports battery backup switching for memory retention during power loss

Supervisors Applications

• Portable instrumentation systems requiring reliable power supervision
• Memory power back-up circuits ensuring data integrity
• Battery operated devices needing low-voltage detection

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Renesas Electronics Corporation, as Intersil was acquired. Check current availability status as some variants may be obsolete or have limited stock. Ensure the operating temperature range meets your application requirements, specifically the +85°C maximum rating for this variant.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required in a compact SOIC-8 package. The adjustable threshold feature allows customization for specific system voltage rails. Consider the open-drain output compatibility with your microcontroller or logic interface. Verify that the 1.8 V minimum supply voltage aligns with your system's active power state.

Supervisors Part Context
