ICL7673CBA

Overview

The ICL7673CBA is a power supply support circuit manufactured by Renesas, originally branded under Intersil. It functions as an OR controller and source selector for managing multiple power inputs. The device is housed in an 8-pin Small Outline Integrated Circuit (SOIC) package with a plastic/epoxy body. It operates within a temperature range of -40 °C to 70 °C and features a single channel with one functional unit. The component is classified under JESD-30 code R-PDSO-G8 and carries an EAR99 classification.

Feature Summary

• Performs OR control logic to manage redundant power sources
• Selects the optimal power input source automatically
• Designed for power supply support applications

Applications

• Redundant power system architectures
• Power supply monitoring circuits
• Source selection in multi-voltage systems

Procurement Notes

Verify compliance status as the component is marked non-RoHS. Confirm the manufacturer origin, noting the transition from Intersil branding to Renesas ownership. Ensure the SOIC-8 package variant matches the specific ordering suffix requirements for your assembly process. Check lead time availability as it may vary by supplier.

Selection Notes

Select this component when designing systems requiring hardware-based power source selection without microcontroller intervention. Consider the 8-pin SOIC footprint constraints and the specified operating temperature range. Verify that the voltage thresholds align with your specific power rail requirements before integration.

Part Context

This part belongs to the ICL7673 family of power management ICs. Originally developed by Intersil, the product line was integrated into Renesas Electronics following corporate acquisitions. These devices are specialized for ensuring continuous power delivery in critical electronics through intelligent source management.

Replacement Considerations

Consult official Renesas documentation for direct pin-compatible replacements or updated equivalents within the current portfolio. Generic substitutes may not replicate the specific OR control logic characteristics.
