ICL7665SAIPA

Supervisors Overview

The ICL7665SAIPA is a CMOS dual voltage detector manufactured by Renesas Electronics. It operates within a supply voltage range of 1.8 V to 16 V and draws a typical operating current of 10 uA. The device features adjustable threshold voltages, with specific overvoltage and undervoltage thresholds documented at 1.325 V and 1.275 V respectively. It provides an active low output signal without manual reset or watchdog functionality. 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 monitoring capability for independent voltage supervision
• Adjustable threshold detection for customizable trigger points
• Low power consumption suitable for battery-operated applications
• Active low output signaling for system reset control

Supervisors Applications

• Portable instrumentation systems requiring voltage supervision
• Memory power backup circuits ensuring data integrity
• Battery operated devices needing under-voltage protection
• Charging systems monitoring input voltage levels

Supervisors Procurement Notes

Verify availability status as the part may be subject to limited supply or end-of-life constraints. Confirm RoHS compliance requirements against project specifications, noting that some sources indicate non-compliance. Ensure the PDIP-8 through-hole package aligns with PCB design constraints. Validate that the specific threshold values meet circuit design needs before procurement.

Supervisors Selection Notes

Select this component when dual voltage monitoring with adjustable thresholds is required in a through-hole package. Consider the wide operating temperature range for industrial environments. Evaluate the low quiescent current for power-sensitive designs. Verify compatibility with the active low output logic level of the downstream microcontroller or system interface.

Supervisors Part Context
