  • Matching MOSFET Drivers to MOSFETs

    There are many MOSFET technologies and silicon processes in existence today, with new advances being made every day. To make a generalized statement about matching a MOSFET driver to a MOSFET based on voltage/current ratings or die sizes is very difficult, if not impossible. As with any design

  • Re: Universal Stepper Driver

    You've replaced the Bipolar junction transistors from #11 with a power MOSFET? That's not going to help. Which circuit diagram are you referencing? As for current limitation, you must also know the complex impedance of your motor to limit the current with a fixed resistor. To make a universal driv...

  • Re: Replacing Traditional Light Bulbs with LEDs

    Hi on7ami, Would this idea be worth developing. The psu for the electronics is a simple cap/resistor dropper, this should work from the ripple of the 325Vdc, if not then feed it from the L230V. This is the way many washing machines etc power their electronics. Then drive a mosfet with your...

  • Replacing A Mechanical Relay With A Mosfet

    I bought a mechanical relay kit to use for a time lapse camera. It works well but I can't use it at night because of the noise it makes. Is it possible to use a mosfet instead? The relay component gets 12v supplied to it on 2 contacts. Here's the diagram.

  • Crossed SMPS MOSFET-based protection circuit for high frequency ultrasound transceivers and transducers

    Background: The ultrasonic transducer is one of the core components of ultrasound systems, and the transducer''s sensitivity is significantly related the loss of electronic components such as the transmitter, receiver, and protection circuit. In an ultrasonic device, protection circuits are commonly used to isolate the electrical noise between an ultrasound transmitter and transducer and to minimize unwanted discharged pulses in order to protect the ultrasound receiver. However, the performance of the protection circuit and transceiver obviously degrade as the operating frequency or voltage increases. We therefore developed a crossed SMPS (Switching Mode Power Supply) MOSFET-based protection circuit in order to maximize the sensitivity of high frequency transducers in ultrasound systems.The high frequency pulse signals need to trigger the transducer, and high frequency pulse signals must be received by the transducer. We therefore selected the SMPS MOSFET, which is the main component of the protection circuit, to minimize the loss in high frequency operation. The crossed configuration of the protection circuit can drive balanced bipolar high voltage signals from the pulser and transfer the balanced low voltage echo signals from the transducer. Methods: The equivalent circuit models of the SMPS MOSFET-based protection circuit are shown in order to select the proper device components. The schematic diagram and operation mechanism of the protection circuit is provided to show how the protection circuit is constructed. The P-Spice circuit simulation was also performed in order to estimate the performance of the crossed MOSFET-based protection circuit. Results: We compared the performance of our crossed SMPS MOSFET-based protection circuit with a commercial diode-based protection circuit. At 60 MHz, our expander and limiter circuits have lower insertion loss than the commercial diode-based circuits The pulse-echo test is typical method to evaluate the sensitivity of ultrasonic transducers. Therefore, we performed a pulse-echo test using a single element transducer in order to utilize the crossed SMPS MOSFET-based protection circuit in an ultrasound system. Conclusions: The SMPS-based protection circuit could be a viable alternative that provides better sensitivity, especially for high frequency ultrasound applications.
