Enabling more effective security systems

A building security system is essential for keeping locations secure and people safe.  These systems can involve a variety of different components such as security cameras or video doorbells, motion detectors, door/window sensors, glass break sensors, electronic locks, and panic buttons. Our analog and embedded solutions help to capture and process data at each node, and our connectivity solutions help these different components communicate with one another, often wirelessly via protocols like Wi-Fi, Bluetooth, Zigbee, Thread, or sub-1 GHz signaling. For battery-powered systems, our low power solutions and efficient, low-Iq power regulators help designers to prolong their system’s battery life for a more convenient user experience.

Smarter sensing and power for greener HVAC systems  

Modern HVAC systems have undoubtedly improved human comfort and quality of life, however, they are often the largest consumer of energy within a building. As designers strive to make HVAC systems more energy efficient, they look to several approaches. Our solutions help to enable use of higher efficiency motors and control techniques such as permanent magnet synchronous motors and variable frequency drives, and our power solutions help to implement efficient power factor correction schemes. Sensing and wireless communications technologies help to boost system efficiencies by more accurately monitoring temperature, humidity, and human occupancy, enabling HVAC systems to be controlled intelligently to meet its heating or cooling needs.

Optimized and accurate smoke detection

Although smoke detectors have long been a critical component of both commercial and residential fire safety systems, they must become increasingly advanced in order to respond to demand for earlier detection of fires, fewer nuisance alarms, compliance to modern regulatory standards, and in some cases additional functionality such as carbon monoxide sensing.  Whether a detector is based on photoelectric sensing or ionization and whether the architecture uses a discrete analog signal chain, dedicated analog front end, or signal chain implemented via an MCU, our solutions are available to help implement accurate smoke detection while maintaining low power consumption to extend lifetimes of battery-powered detectors.
