How to Fast-Charge your Supercapacitor
Supercapacitors (or ultracapacitors) are suited for short charge and discharge cycles. They require high currents for fast charge as well as a high voltage with a high number in series as shown in two usage cases: an automatic pallet shuttle and a fail-safe backup system. In these and many other cases, the fast charge is provided by a flexible, high-efficiency, high-voltage, and high-current charger based on a synchronous, step-down, supercapacitor charger controller.

Don’t Get Cold Feet with Your ASIL-B, Cold-Crank Specifications
In this design solution, we show how a TFT-LCD display backlight can meet the automobile’s toughest requirements. We demonstrate how the automotive backlight driver offers comprehensive diagnostics, I2C capability, and critical circuit redundancy that meet ASIL-B functional safety requirements. A clever design allows the MAX25024 to meet and exceed cold-crank specification for flicker-free automotive display operation. High integration yields a small IC, lower BOM costs, and smaller PCB size.

Make Your Automotive Dual USB Type-C Power Delivery Design Cool and Flexible
This design solution reviews the challenges of designing an automotive dual USB Type-C power delivery system. The module temperature rise must be below 40°C. The automotive battery voltage undergoes wide swings. The data lines must be adequately protected, and the design must be flexible and adaptable to different form factors. A buck-boost controller IC and a protection IC chipset enable a small and flexible module that must operate within allowed thermal limits.
