Abstract

In the realm of automotive design, particularly in Electric Vehicle/Hybrid Electric Vehicle (EV/HEV) applications, there is an increasing necessity to make sure that I/O signals do not short to the battery voltage, often referred to as V_BAT. It is crucial to prevent damage resulting from a Short to Battery condition, which is of utmost importance in automotive environments where safety is paramount. The following application note dives into how Texas Instruments' analog switches and multiplexers can be leveraged to mitigate system damage by using a concept known as Short to Battery Protection.
