Efficient, space-saving solutions Littelfuse offers for wireless charging system power adapters and charging cables appear in this block diagram. Options to reduce component count without compromising performance include MOSFETs for current conversion and Schottky diode rectifiers for current output. We also make digital temperature indicators to prevent thermal damage to cable connectors.

Power for wireless charging pads comes from proprietary dc inputs or USB ports. This block diagram shows Littelfuse products can protect input circuits and ports from current overloads, transient voltage surges, and thermal damage. We produce fast-acting thin film chip fuses, TVS diodes, and digital temperature indicators well-suited to provide that protection.
