This demo shows the maximum range of a typical fob as a function of “gain mode” and “driver current”.


Value Propositions

* The combination offers a maximum LF distance for convenience functions such as welcome light, walk-away locking or distance bonding

* 3 best in class gain/sensitivity modes on the key side offer full freedom of design for any use case

* Maximum distances of up to 10m in LF range can be achieved.
