RE46C127E16F

Sensor And Detector Interfaces Overview

The RE46C127E16F is a CMOS ionization smoke detector ASIC designed for standalone or interconnected alarm systems. It operates on a supply voltage range of 6V to 12V with typical standby current consumption below 6.5uA at 9V. The device features an internal oscillator that powers detection circuitry for 10.5mS every 1.66 seconds, enabling low quiescent power usage. It includes interconnect capability for up to 40 detectors and an 8-minute timer mode for sensitivity control. The IC supports temporal tone output and is recognized by Underwriters Laboratories per UL217 and UL268 specifications.

Sensor And Detector Interfaces Feature Summary

Sensor And Detector Interfaces Procurement Notes

Verify the specific package variant required, as the base part number covers both PDIP-16 and SOIC-16 packages. Confirm RoHS compliance status during ordering, as packaging options include standard and lead-free variants. Ensure the selected suffix matches the desired physical footprint for PCB layout compatibility.

Sensor And Detector Interfaces Selection Notes

Select this component for designs requiring low standby current in ionization smoke detectors. Consider the PDIP-16 or SOIC-16 package based on assembly method. Verify external component values for RBIAS and OSCAP to ensure accurate oscillator timing and sensitivity settings according to the application notes.

Sensor And Detector Interfaces Part Context

The RE46C127 belongs to the Microchip R&E International family of smoke detector ASICs. It is specifically engineered for ionization chambers, distinguishing it from photoelectric counterparts like the RE46C14x series. The E16F suffix typically denotes the PDIP-16 package variant within this product line.
