CS235 Datasheet (Cherry Semiconductor Corporation) - System Photoelectric Smoke Detector

CS235, System Photoelectric Smoke Detector

The CS235 System Smoke Detector is a photo electric type with a pulsed infrared LED as the light source and a silicon photodiode as the light detector.

The CS235 IC, along with passive external components, controls the system timing and signal processing.

Low average current is attained by pulsing t

CS235 Features

* include an ICC current limiter. The current limiter eliminates power-on false alarming. The oscillator controls the IR LED excitation frequency and provides drive to the synchronous detector. The synchronous detection method has very high noise rejection performance. The internal latch is capable of
