Reference design – USB Type-C charger delivers 18W
Graham Prophet @ eedesignnewseurope.com discuss about a 18W USB power supply reference design. This joint reference design describes an 18W, USB PD compliant, AC-DC power converter. The design, titled DER-567, pairs the WT6630P USB Type-C PD controller from Weltrend with Power...

Beacon Keyer
Lukas Fässler from Soldernerd published a project showing how he built a PIC-based beacon keyer: This is likely the first ham radio related project that I document here on this blog But my very first PIC project was a beacon keyer that I made for my father, HB9BBD. That was in...

Current Sensor Amplifier & Over Current Switch
Current sensor amplifier and over current switch project is based on ACS714-30A current sensor and LM358 Op-amp, ½ of LM358 op-amp used as an amplifier for low voltage and 2nd 1/2 LM358 op-amp used as comparator which provides over current TTL output, trimmer potentiometer...

FPGAs For MCU Guys
by Max Maxfield @ eeweb.com: A little while ago, it struck me that I was getting tired of explaining what FPGAs are and how they work their magic to those of my chums who — thus far — have worked only with microcontrollers (MCUs), so I decided to write a three-part mini-series of...

Fuel gauge needs no battery characterization
by Susan Nordyk @ edn.com The MAX17055 single-cell fuel gauge from Maxim not only eliminates battery characterization, but also keeps SOC (state-of-charge) error to within 1% in most scenarios. With its ModelGauge m5 EZ algorithm, the device provides tolerance against battery...
