ICL7665SAIPAZ

Supervisors Overview

The ICL7665SAIPAZ is a CMOS supervisory circuit manufactured by Renesas Electronics (formerly Intersil). It functions as a dual-channel voltage detector with adjustable thresholds, monitoring two independent input lines. The device operates within a supply voltage range of 1.8 V to 16 V and draws a typical operating current of 10 µA. It features an active-low output type and lacks manual reset or watchdog timer capabilities. The component is housed in an 8-pin PDIP package and is rated for operation between -40°C and +85°C.

Supervisors Feature Summary

• Dual-channel voltage monitoring capability for independent power rails
• Adjustable threshold voltage settings for flexible detection levels
• Low-power CMOS design suitable for battery-backed systems

Supervisors Applications

• Power supply support circuits requiring dual voltage supervision
• Embedded systems with critical over/under-voltage protection needs
• Battery backup switching applications

Supervisors Procurement Notes

Verify the specific suffix 'SAIPAZ' against official Renesas documentation to confirm the PDIP-8 through-hole package variant. Ensure compatibility with existing board layouts designed for DIP-8 footprints. Confirm that the active-low output logic aligns with the target microcontroller or system interface requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required with low quiescent current consumption. The adjustable threshold feature allows customization for specific rail voltages. Consider the PDIP-8 package constraint if surface-mount space is unavailable. Verify that the absence of a manual reset pin does not conflict with system startup sequences.

Supervisors Part Context

The ICL7665 series belongs to Renesas' portfolio of micro-power voltage detectors. This family provides reliable supervision for single or multiple power rails in industrial and consumer electronics. The ICL7665SAIPAZ represents the through-hole version of the broader ICL7665S line, maintaining functional parity with surface-mount variants while offering different mounting options.

Supervisors Replacement Considerations

ICL7665SCBAZA is a documented parameter-equivalent alternative from Renesas, though it utilizes an SOIC-8 surface-mount package rather than the PDIP-8 form factor.
