Product Description

The **RE46C119S16TF** is a **Smoke detector IC** from **Microchip**, designed for integration into fire safety systems. Housed in a **SOP-16 sensor component** package, it features dual inputs for sensor signal processing and multiple outputs for driving alarms (buzzer/LED). This IC operates at 2V–6V, supports a wide temperature range (-40°C to +85°C), and is ideal for residential/commercial smoke detectors. Key advantages include ultra-low standby power consumption (<1µA) and high sensitivity optimization, though it lacks built-in communication interfaces, relying on simple I/O control. The **RE46C119S16TF datasheet** recommends pairing it with external ionization or photoelectric sensors for 5–15m detection range. Typical applications involve 9V battery-powered systems (battery capacity depends on design), with no integrated screen. Its compact SOP-16 form factor enables seamless integration into space-constrained modules.
