Programmable 3D Low Frequency Wakeup Receiver AS3932 APPLICATION NOTE

1 Introduction The development kit has been thought to speedup the system design phase in finding the best setup of the LF-Wakeup receiver AS3932, without spending time in the hardware design. The development-kit consists of a AS3932 LF wake-up receiver board, a 3V CR2032 Lithium Battery, a LF transmitter board and a 9V power supply. The power supply cable is not included and has to be chosen according to the specific plug (depending on the......

Low Consumption Flux-gate Transducer for AC and DC high-current Measurement

  Abstract—This work presents the design and implementation of a transducer system for the measurement of AC and DC high-current using the flux compensation technique in the measurement transformer, also called Flux-gate technology. The system can measure currents greater than 700 A (peak value) with a 100 kHz bandwidth measured at -3 dB. This equipment has been developed under the agreement of collaboration subscribed between......

Premo RIFD Transponder Coils for TPMS application

1.    Introduction   Basic functionality of TPMS (Tire Pressure Monitoring System) is to monitor tire inflation pressure and temperature. Most of TPMS are attached to the valve. Transponder coils acts as the media to transmit information to wake-up the system. Tipically all information concerning pressure and temperature are transmitted to “central electronic box) through RF interface (tipically 433MHz). ......

AIC Series improves in efficiency and design the competitor’s high energy storage chokes

Standard solutions used in power applications to convert DC waveforms to AC waveforms are known as inverters. These products are used in Uninterruptable Power Supplies (UPS); in frequency converters that convert the alternating current (AC) in direct current (DC), to modulate it afterwards in a variable frequency; in inverters used to generate alternating current from direct current sources, supplied by batteries or renewable energies sources, like eolic turbines or solar......
