Overview
The Intersil ICL7673CPA is a monolithic CMOS battery backup circuit designed for automatic switching between primary and secondary power sources. It operates within a voltage range of 2.5V to 15V. The device is housed in an 8-pin PDIP package with dimensions of 0.300 inches (7.62mm) width. It functions as a power supply support circuit, ensuring continuous operation during main power failure by seamlessly connecting to a backup battery.
Feature Summary
- Monolithic CMOS construction for reliable battery backup switching
- Automatic transition between primary and secondary power sources
- Operates across a wide input voltage range from 2.5V to 15V
Applications
- Automatic battery back-up switch systems
- Power supply support circuits requiring seamless source selection
- Battery management applications needing primary/secondary power switching
Procurement Notes
Verify the specific suffix 'CPA' corresponds to the 8-PDIP package configuration. Confirm that the component meets required environmental standards, noting that some listings indicate non-compliance with certain regulations. Ensure compatibility with the intended voltage range of 2.5V to 15V before integration into the design.
Selection Notes
Select this component when a dedicated monolithic solution for automatic battery backup is required. The CMOS technology offers advantages over conventional switching methods. Consider the 8-PDIP package constraints and the specified operating temperature range when designing the PCB layout and thermal management strategy.
Part Context
This part belongs to the Intersil ICL7673 series, which includes variants like the ICL7673CBA in SOIC-8 packaging. The ICL7673CPA specifically denotes the PDIP package version. The series is recognized for its role in power supply support, providing a compact alternative to discrete switching components.
Replacement Considerations
Check for direct substitutes within the ICL7673 family, such as the ICL7673CBA, if package flexibility exists. Verify pinout compatibility and electrical specifications against any alternative battery backup switches to ensure functional equivalence without redesigning the surrounding circuitry.
