\section*{AMS \& IMD latching}
The latching is achieved with the MC14013BDG flip-flop. It can only be resetted by the AMS reset button in the error state. (the Reset\_Button\_In and Reset\_Button\_Out comes directly from the button located on the side of the car.)

\section*{Current Consumption}
To calculate the current consumption, the load on the shutdown circuit must first be identified. As seen in the SDC schematic, the load consists of the AIRs, precharge relay, EBS Relay and the Discharge Circuit.

\subsection{IMD Latching}
\begin{itemize}
\begin{itemize}
\item The \texttt{IMD\_OK} signal is pulled high approximately 1.5 seconds after startup for the \href{https://www.bender.de/fileadmin/content/Products/d/e/IR155-32xx-V004_D00115_D_XXEN.pdf}{IR155-3204 IMD}.
\item Therefore the Power-on Reset (PoR) lasts approximately 2 seconds.
\end{itemize}
\end{itemize}
\subsection{AMS Latching}
\begin{itemize}
\begin{itemize}
\item The \texttt{AMS\_OK} signal is pulled low until the following conditions are met:
\begin{itemize}
\item The AMS Master communicates with all six AMS Slaves, each providing valid voltage and temperature measurements.
\item The AMS Master communicates with the shunt sensor (\href{https://www.isabellenhuetteusa.com/wp-content/uploads/2022/07/Datasheet-IVT-S-V1.03.pdf}{IVT-S-300-U3-I-CAN2-12/24})

Both signals are transmitted every 50 ms over the CAN bus. If the Dashboard does not receive a CAN message from the AMS Master within 150 ms,
it will trigger a fault condition. In response to this fault, the following LEDs will be activated:
