We’re fortunate to live in a world where ceiling-mounted smoke detectors are commonplace. These are essential for residential safety, and they require efficient electronic components that can prolong battery life and be highly reliable.
Our market-leading smoke detector interface ICs offer power-saving features in a single-IC solution responsible for monitoring a photo-electric or ionization chamber. With high levels of integration, our ICs are keeping you safe- sounding the alarm, testing and reporting on battery life, and monitoring for proper serial unit interconnectivity.
The A5303 is a low-current photoelectric smoke detector circuit with ultra-low standby current and can operate for 10 years powered by inexpensive batteries. The A5366 and A5358 are a low-current sensing IC’s that provide all of the required features for a photoelectric type smoke detector.
