ON Semiconductor has extended its industrial integrated circuit (IC) offering with a range of new devices offering a high degree of robustness, supporting a wide operational temperature range, and possessing strong performance levels while consuming minimal power.
KNX transceiver
The NCN5120 transceiver 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. It has a built-in 20 V voltage regulator and two high-efficiency DC-DC converters.
The first converter features a fixed output voltage of 3,3 V, while the second provides an adjustable output voltage between 3,3 V and 21 V. This device is ideal for high-power applications such as smart lighting systems, ventilation/air conditioning systems, thermostats, smoke detectors and alarm systems.
GFI controllers
The NCS37000, NCS37005 and NCS37012 are ground fault interrupter (GFI) controllers capable of carrying out the signal processing activities associated with GFI applications.
Supporting 6 V to 18 V operation and with a power consumption of just 5 mW, these devices integrate a flexible power supply, including shunt and low dropout (LDO) voltage regulators. They offer differential fault detection circuits and have a built-in grounded neutral detect function.
ON Semiconductor’s proprietary fault processing circuitry allows high performance to be achieved with a single low-turns-ratio current transformer. These devices are compatible with low-cost ferrite current transformers and have been highly optimised for load panel breaker and GFI receptacle applications. The NCS37012 incorporates a comprehensive self-test circuit that is compatible with the emerging UL mandated self-test standard.
VLDOs
The NCP59300, NCP5915x, NCP57152, NCP57302 and NCP58302 are high-precision, high-current, very low dropout (VLDO) voltage regulators with a 1,8 V minimum input voltage, an output current of 3 A and low ground current characteristics.
The NCP59300, NCP5915x and NCP57152 can deliver typical dropout voltages below 300 mV for a 3 A load current, while the NCP57302 and NCP58302 deliver 315 mV and 370 mV respectively at this load current.
These devices can all withstand up to 18 V (maximum) input voltage and have built-in thermal shutdown and reverse output current protection features. They are highly suited to use in industrial power supplies and process control systems, as well as data/telecommunications infrastructure and automotive modules.
IGBTs
With current ratings up to 40 A, the NGTB40N120FLWG, NGTB25N120FLWG and NGTB15N120FLWG IGBTs feature low switch losses and include an ultra fast recovery diode, making them ideal for high-frequency solar, UPS and inverter welder applications.
The NGTB30N120LWG and NGTB40N120LWG are suited for hard switching applications such as motor control inverters, while the NGTB30N120IHLWG, NGTB40N120IHLWG, NGTB20N120IHSWG and NGTB30N120IHSWG offer balancing switching and conduction losses for induction heating and other soft switching applications including hot pots, rice cookers and microwave appliances.
