Boasting a power rating of 100 W, ST’s STWLC99 wireless power receiver can recharge high-end smartphones with the largest battery capacity in under 30 minutes. In addition to smartphones, the STWLC99 offers new opportunities for medical devices…

Hot resistance versus cold resistance

Incandescent lamp filaments have ratios of hot resistance versus cold resistance that really startled me even though I thought I knew all about such things. It turns out I did not know “all about” and the consequences of my ignorance were…

Resolution explained for magnetic angle sensors

Because optical encoders are functionally similar, “resolution” is often used as a main characteristic for magnetic encoders, a device providing the angle of a magnet attached to a mechanical shaft under a digital form. Resolution is a key…

Microphones: An abundance of options for capturing tones

Having just covered the topic of speaker construction (specifically as it relates to in-ear headphones), both in one of last month’s blog posts and one of the prior month’s teardowns, I thought now would as good a time as any to tackle the…

Hall effect split-core current sensor calibration station

Recently, I’ve been working on a solar off-grid monitoring system. In the system are a few split-core Hall effect sensors to monitor DC current in the solar panel current, the battery charge current, and the inverter input current. These currents…

Fundamentals of I3C interface communication

I3C is a new serial communication protocol for embedded systems that offers significantly higher data throughput and more advanced features than I2C. With I3C, engineers and designers can improve the performance of their designs while also adding…
