I. Overview

Stay Powered on the Go: Protected USB port on the motorcycle with the LDP01-28AYD2-AQ from Diotec

As spring arrives and the days get longer, many motorcyclists take their bikes out of storage and hit the road. A smartphone is a must-have accessory, as there are apps available to help bikers navigate, find the best and cheapest fuel stops, and provide weather information for the route.

On longer journeys, the smartphone battery may run out. You can easily charge your smartphone using the USB port in the cockpit. Like all electronics in a vehicle, it must be protected against load-dump events. These are voltage peaks on the board mains, occurring typically in the case of a jump start. When the supplying battery is disconnected under load, the jumper cables act like an ignition coil. Here, the Load Dump Protector LDP01-28AYD2-AQ by Diotec Semiconductor comes into play. According to ISO 16750-2 load dump curves, it offers protection and clamps its peaks to safe levels. The device is fully AEC-Q101 qualified and comes in the powerful D²PAK case outline.
