Description

This reference design shows example implementations of how to handle a variety of high-voltage (HV) switch inputs using a multi-switch detection interface (MSDI) device. This user's guide gives real-world examples of a MSDI device handling HV switch inputs for body control module (BCM), faceplate, and top column module (TCM) applications. In addition, the design utilizes a wide-VIN low-dropout (LDO) regulator for creating a fixed 3.3-V microcontroller supply voltage.
