One, toggle mode, permits on/off touch control for example for light switch replacement. Another makes the sensor output a pulse instead of a DC level, which allows the device to 'talk' over the power rail, permitting a simple 2-wire twisted-pair interface. Quantum’s unique HeartBeat™ signal is also included, allowing a host controller to continuously monitor sensor health. By using the charge transfer principle, these ICs deliver a level of performance clearly superior to older technologies in.
