Rechargeable battery fuel gauges keep users of notebook computers, smartwatches and other wearable devices, wireless headsets and speakers, and mobile point of sale systems know when to charge. Ensuring the gauge operates optimally requires high-performance temperature sensors, overcurrent protection, and overvoltage protection. Littelfuse supplies those electronic solutions.

From USB charging ports to joysticks, Littelfuse offers electronic solutions for video game controllers. Our TVS diode arrays, eFuses, and resettable PPTC devices provide comprehensive overcurrent and overvoltage protection. We also supply overtemperature protection for battery packs in wireless game controllers, as well as tactile switches and thumbstick switches for controllers of all types.

Smartwatches, wireless headsets, and other wearables require efficient batteries that charge quickly without overheating. Littelfuse offers mobile battery protection solutions that help product designers comply with IEC and UL standards.

The types and capabilities of wearable electronic devices keep growing. Electronic components made by Littelfuse enable smartwatches, VR and AR systems, and wireless headsets operate safely, efficiently, and with long battery lives. Our solutions for mobile wearables include ESD protection for touchscreens, electromechanical switches for user controls, and thermal protection for USB chargers.

Hardwired point of sale (POS) terminals and mobile POS (mPOS) systems increasingly incorporate wireless connectivity. As these technologies evolve, so must battery packs, motherboards, power adapters, printers, and other electronic components. Trust Littelfuse to deliver custom and off-the-shelf electronic components that help ensure reliable POS equipment operations.

A wireless charging system consists of a power adapter, a charging cable, and a charging pad. The power adapter converts ac voltage from the power line into dc voltage. The charging cable sends power from the adapter to the charging pad. The charging pad then transmits power wirelessly to the device-to be-charged. Design safe and reliable wireless charging systems with Littelfuse solutions.
