Silicon Laboratories Si114x IR Sensor ICs and Evaluation BoardSi114x IR Sensor ICs and Evaluation Boards
The QuickSense™ Si114x series ICs from Silicon Labs are the industry’s most sensitive and lowest power active infrared proximity and ambient light sensor ICs. The monolithic Si114x family of devices features an all digital I²C control interface and up to three infrared LED drivers in an impressively small 2mm x 2mm clear QFN package. Capable of controlling one, two, and three infrared LED systems, developers have the freedom to implement one-dimensional systems with a range of up to 50cm or multi-dimensional systems capable of advanced motion sensing with a range of up to 15cm.

Silicon Laboratories Si85xx Unidirectional AC Current SensorsSi85xx Unidirectional AC Current Sensors
The Si85xx products are unidirectional AC current sensors available in full-scale ranges of 5A, 10A, and 20A. Si85xx products are ideal upgrades for older current sensing technologies offering size, performance, and cost advantages over current transformers, hall effect devices, DCR circuits, and other approaches. The Si85xx are extremely low-loss, adding less than 1.3mOhm of series resistance and less than 2nH series inductance in the sensing path at 25°C. Current-sensing terminals are isolated from the other package pins, providing up to a 5kV RMS isolation level per safety approval ratings.
