RE46C190S16F Description

Short technical summary and product information.

The RE46C190S16F from Microchip Technology is a CMOS photoelectric-type smoke detector integrated circuit designed for low-power applications. It operates on two AA batteries and features internal power-on reset and low quiescent current consumption.

 

This IC incorporates a gain-selectable photo amplifier for use with an infrared emitter/detector pair. An internal oscillator strobes power to the detection circuitry every 10 seconds to minimize standby current. If smoke is detected, the rate increases to verify an alarm condition. A high gain mode is available for chamber testing.

 

Key features include local alarm memory, interconnect capability for up to 40 detectors, and a 9-minute timer for sensitivity control. It supports temporal or continuous horn patterns and includes internal low battery and chamber testing functions. The RE46C190S16F is designed for smoke detectors complying with UL217 and UL268 specifications.

 

The device is housed in a 16-SOIC package and is designed for surface mount applications. It operates within a temperature range of -10°C to 60°C and has a typical supply current of 1 µA.
