electronica 2012: ON expands portfolio of industrial ics

ON Semiconductor has introduced the NCN5120 KNX transceiver, a new device which supports the transmission and reception of data on a twisted pair network bus and is compliant with the KNX standard for home and building automation.

The module has a built in 20V voltage regulator and two dc/dc converters. The first converter features a fixed output voltage of 3.3V, while the second provides an adjustable output voltage between 3.3 and 21V. Typical applications include smart lighting systems, ventilation/air conditioning systems, thermostats, smoke detectors and alarm systems.

The NCS37000, NCS37005 and NCS37012, also being introduced at electronica 2012, are ground fault interrupter (GFI) controllers capable of carrying out the signal processing activities associated with GFI applications.

Supporting 6 to 18V operation and with a power consumption of 5mW, the devices integrate a flexible power supply, including shunt and low drop out voltage regulators. They offer differential fault detection circuits and have a built in grounded neutral detect function. The devices are compatible with low cost ferrite current transformers and have been optimised for load panel breaker and GFI receptacle applications.

In addition, the NCP59300, NCP5915x, NCP57152, NCP57302 and NCP58302 are high precision, high current, very low drop out (vldo) voltage regulators with a low minimum input voltage (1.8V) and output current of 3.0A. The NCP59300, NCP5915x and NCP57152 can deliver typical drop out voltages below 300mV for a 3.0 A load current, while the NCP57302 and NCP58302 are optimised to deliver 315 and 370mV respectively.

The devices can all withstand up to 18V (maximum) input voltage and have built in thermal shutdown and reverse output current protection features. According to ON, they are suitable for use in industrial power supplies and process control systems, as well as data/telecommunications infrastructure and automotive modules.
