Abstract

Electronic shifters (E-shifter) determine the operating modes of a vehicle and therefore require robust redundancy built into them to make sure critical function is maintained despite whatever glitches can occur. For that redundancy, many manufacturers design with identical independent sensing devices. This document details how the TMAG5170D, which has two independent sensing devices integrated into a single package, can be used to design an E-shifter.
