@copilot I need to break down this circuit diagram into functional blocks. Please analyze the it, identify the different functional parts and DO NOT ASSUME ANY PART/COMPONENT. Here is a list of common module names: Power Supply Functional Blocks

Amplifier Functional Blocks

Oscillator Functional Blocks

Filter Functional Blocks

Signal Processing Functional Blocks

Signal Conditioning Functional Blocks

Modulation and Demodulation Functional Blocks

Communication Functional Blocks

Control Functional Blocks

Sensor Interface Functional Blocks

Protection Functional Blocks

If you find a part relevent to a perticular module name then you use it otherwise you do not use it. Create individual tables for each identified module with the following details: Module Name

What do we have for voltage spike protection?

copilot

For voltage spike protection in the circuit, the following components are used:

Protection Functional Blocks

Module Name	Components	Description of Functionality	Connections and Interactions with Other Modules
Protection	D1, D2	Provide ESD and transient voltage spike protection for CAN bus lines.	- D1 (NUP2105L): Protection diode connected to CANH2 and CANL2 lines. - D2 (NUP2105L): Protection diode connected to CANH1 and CANL1 lines. - Connects to CANBUS lines and ground, providing clamping for voltage spikes on the CAN lines.

Voltage Spike Protection Details

D1 (NUP2105L):
- Connections:
  - $D1:K1$ to $CANBUS2:P2$
  - $D1:K2$ to $CANH2:P1$
  - $D1:A$ to GND
D2 (NUP2105L):
- Connections:
  - $D2:K1$ to $CANBUS1:P2$
  - $D2:K2$ to $CANH1:P1$
  - $D2:A$ to GND

These diodes are designed to clamp voltage spikes and prevent high voltage transients from damaging the sensitive electronics in the CAN transceiver and other connected components. They typically handle ESD and other transient events that can occur on CAN bus lines in automotive and industrial environments.
