After discussing the three transistor high-side buck p-mosfet driver (a recognised circuit and not mine) with some of EW’s sage commenters, I wondered once again if I could design something similar ...

Traditional relay drivers involve multiple discrete components to drive the relay and protect against damage to the microcontroller or other devices that can be caused by the voltage spike generated ...

Single-coil latching relays find use in signal-routing, audio, and automotive systems. To maximize their usefulness and cut power consumption, these coil currents must flow in both directions. Current ...
