\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.
|
|
The current consumption of the components are as follows:
|
|
|
|
\begin{multicols}{2}
|
|
\begin{itemize}
|
|
\item AIRs: \SI{249}{\milli\ampere} \cite{air_datasheet}
|
|
\item Precharge relay: \SI{8}{\milli\ampere} \cite{precharge_datasheet}
|
|
\item EBS relay: \SI{9.6}{\milli\ampere} \cite{ebs_datasheet}
|
|
\item Discharge circuit: \SI{4}{\milli\ampere} \cite{discharge_datasheet}
|
|
\end{itemize}
|
|
\end{multicols}
|
|
|
|
We can then find the total consumption when we add all the the load together. $\SI{249}{\milli\ampere} \cdot 2 + \SI{8}{\milli\ampere} + \SI{9.6}{\milli\ampere} + \SI{4}{\milli\ampere} \approx \SI{520}{\milli\ampere}$.
|
|
|
|
\section*{Overcurrent Protection}
|
|
The overcurrent protection is achieved with a physical fuse and a power switch (Infineon PROFET$^{\text{TM}}$ \cite{profet_datasheet}) on our PDU (Power Distribution Unit) PCB. The 3557-15 in the schematic is the fuse-holder for the 1A fuse, and the BTT6050-1ERA is the PROFET$^{\text{TM}}$.
