Sensor And Detector Interfaces Procurement Notes

Verify the specific package type (DIP or SO) required for your design, as the base part number covers multiple packaging options. Confirm RoHS compliance status if lead-free materials are mandatory for your assembly process. Ensure the ordering suffix matches the exact pin configuration and environmental rating needed for production.

Sensor And Detector Interfaces Selection Notes

Select this component when designing circuits requiring integrated horn and LED driving capabilities with minimal power consumption. Consider the 20Ω typical driver Ron and 100nA quiescent current for battery-operated applications. Verify that the 6V to 16V supply voltage range aligns with your system's power architecture and that the 0°C to 50°C operating temperature meets environmental requirements.

Sensor And Detector Interfaces Part Context

The RE46C101 series is part of Microchip's portfolio of specialized analog interface circuits designed for sensor and detector applications. Originally developed by R&E International, now a subsidiary of Microchip, these devices combine signal processing with power driving functions. This specific model targets low-power acoustic signaling and visual indication in safety and consumer electronics.

Sensor And Detector Interfaces Replacement Considerations

Check for direct replacements within the RE46C10x family, such as the RE46C100 or RE46C104, depending on whether LED driving functionality is required. Verify pin compatibility and electrical characteristics before substitution.
