Simplify Your Embedded Designs Using I²C I/O Expanders

The I²C two-wire bus is still as popular today as when Philips originally invented it in 1982. Initially operating at 100KHz, the latest incarnation, version 7 (2021) Ultra-Fast-mode (UFm), now clocks at 5MHz—making it fast enough for most medium-speed peripherals, including digital I/O, GPIO, keyboards, keypads, and sensors.

Use a ReDriver or ReTimer for Longer and Thinner USB, USB Type-C, and DP Cables

USB, USB Type-C®, and DisplayPort™ (DP) cables have become so ubiquitous as to even be purchased in low-cost convenience stores. However, while two individual cables may appear identical to the naked eye, they can differ considerably in the quality of performance they provide. Low cost can mean low quality, and alongside instances where cheap cables have caused electronic equipment to malfunction or have corrupted data, they typically cause poor picture quality or slow down the rate of data transfer to well below the multi-gigabit bandwidth offered by the latest USB specification (USB 4).

Plug-and-Play USB Charging Controller Makes Charging of Battery-Powered Devices Seamless

In the not-too-distant past, it seemed like every electronic device had its own custom power supply, cable, and interface (Figure 1). USB Type-C® (or USB-C®), which implements the USB power delivery (USB-PD) specification, was supposed to solve this problem by introducing a single standard interface that all devices could use.

How Piezo Sounder Drivers Increase Sound Pressure Levels Across a Wider Battery Voltage Range

Piezo sounders create warning or alert noises in many applications, oftentimes in portable, battery-powered, and space-saving products. These devices consist of a ceramic element attached to a metal plate, where the ceramic element uses the piezoelectric effect to distort its shape when a voltage is applied. As it contracts and expands due to the varying voltage, the attached plate vibrates audibly.
