Abstract

Wireless power is gaining popularity in modern electronics. Automotive devices are no exception. Automotive devices such as remote keyless entry keyfobs, fleet management systems, and asset tracking are applications where a charger paired with a wireless receiver can improve the overall system by moving to a wire-free implementation of power delivery. This application note shows the implementation of the BQ25171-Q1 and the BQ51013B-Q1 in a test friendly layout for evaluation prior to incorporating both of these devices into a design.
