A generally accepted fact about relays and solenoids is that after they’re driven into the actuated state, only half as much coil voltage and therefore only one fourth as much coil power, are required to reliably sustain it...

The L99H92 automotive gate driver from STMicroelectronics provides an SPI port for programming and diagnostics, a charge pump, protective features, and two additional current-sense amplifiers for system monitoring...

This article details a method of generating dual-output voltage rails that provide both the positive and negative rails for a device power supply while requiring only one bidirectional power supply...

While an internal, rechargeable lithium battery is usually the best solution for portable kit nowadays, there are still times when using replaceable cells with an external power option, probably from a USB source, is more appropriate...

Self-heated transistors used as thermal air flow sensors are a particular (obsessive?) interest of mine, and over the years I must have designed dozens of variations on this theme...

Many PWM applications, such as Class D audio amplifiers, require symmetric drive circuitry...

Integration of analog circuitry with digital logic often requires the addition of an extra supply rail or two...

While the long-lived Z80 continues on in Z180 and eZ80 forms, the standalone DIP-packaged variants' days are numbered...

This article will explain the inherent limitations of the boost topology and how to overcome them...

You would normally limit the inrush current during start-up of a rectifier circuit with a capacitor output filter...
