Introduction to Field Effect Transistor (FET) Field effect transistor, abbreviated as FET, is a semiconductor device that uses electric field effect to control current. Unlike traditional bipolar transistors (BJTs), FETs are only conducted by majority carriers (electrons or holes), hence they are called unipolar transistors. 2、 The working principle of FET field-effect transistor is mainly composed of three regions: gate, drain, and source. In normal operating conditions, the gate voltage controls the current between the source and drain, thereby achieving control over the field-effect transistor. Cut off state: When the gate voltage is lower than the threshold voltage, there is no conductive channel between the gate and the channel, and electrons cannot flow from the drain to the source. The field-effect transistor is in a cut off state, equivalent to an insulator. Conduction status:

1、 CAN Introduction 1.1 What is CAN? The CAN (Controller Area Network) bus protocol is a serial communication bus based on message broadcasting mode invented by BOSCH. It was initially used to achieve reliable communication between ECUs in automobiles, but due to its simplicity, practicality, and reliability, it has been widely used in other fields such as industrial automation, ships, and healthcare. Before understanding the CAN bus protocol, we need to know what automotive ECU refers to? ECU (Electronic Control Unit), also known as the "onboard computer" of a car, is used to control the driving status of the car and achieve its various functions. It mainly uses various sensors and buses for data collection and exchange to determine the vehicle status and the driver's intention, and controls the car through actuators. Simply put

1、 Understanding of Transistors 1.1 Understanding of Commonly Used Transistors (1) Meaning: The full name of a transistor is a "crystalline transistor", also known as a "transistor". It is a typical semiconductor component. The three poles of a transistor: base (b): used to activate the transistor collector (c): the positive pole of the transistor (collecting charge carriers) emitter (e): the negative pole of the transistor (emitting charge carriers) base current controls the current between the collector and emitter. (2) Types ① Common transistors can be mainly divided into two categories based on their polarity structure: NPN type and PNP type. PNP transistor: composed of two series connected crystal diodes. NPN transistor: Basically used to amplify weak signals into strong signals According to different power levels, transistors can be divided into low power, medium power, and high power.

1、 LIN Introduction 1.1 What is LIN? LIN (Local Interconnect Network) bus is a low-cost serial communication protocol defined for automotive distributed systems. Compared to CAN bus, LIN bus protocol is relatively simple and does not require high requirements for microcontrollers. Basic serial ports can be implemented, so the cost is lower. As an auxiliary bus of CAN bus, LIN bus is a supplement to existing bus technology and is widely used in vehicle control fields such as doors, windows, headlights, and central locking. The characteristics of the 1.2LIN bus are that the single master/multi slave device mode does not require arbitration mechanism and is low-cost. Based on UART serial communication, all control machines have the necessary hardware for LIN. One master node corresponds to multiple slave nodes for single signal line transmission, while ensuring that the delay time of signal transmission LIN is predictable

1、 Understand diode 1 What is a diode? A diode is a commonly used semiconductor device, which is composed of a P-N junction formed by a P-type semiconductor and an N-type semiconductor, with corresponding electrode leads led out at both ends of the P-N junction, and sealed with a tube shell. 2. Common structures of diodes: (1) Point contact type: small junction area, small junction capacitance, so the allowed current of the junction is small, and the highest operating frequency is high. (2) Surface contact type: With a large junction area and capacitance, the junction allows for a high current and a low maximum operating frequency. (3) Flat type: The junction area can be small or large, with small junctions having high operating frequencies and large junctions allowing for large currents. 3. Classification of diodes There are many types of diodes, and according to their actual functions, common diodes can be divided into rectifier diodes, voltage regulator diodes, and detector diodes

Preface: The basic knowledge of CAN was introduced in the detailed introduction of CAN before, but due to the disadvantages of low communication rate, long message header, and low refresh rate of CAN bus. CAN FD has emerged to address these issues. 1、 Introduction to CANFD: CAN FD (CAN with Flexible Date rate), also known as "Variable Rate CAN", supports faster data transmission rates and larger data loads. It is an evolved version of the CAN bus that can be used to support applications with higher bandwidth. For example, advanced driver assistance systems (ADAS) and autonomous driving systems (AV) (note: CAN FD has only upgraded the protocol compared to CAN, and the physical layer has not changed.) 2. Why is CAN FD needed? 1. Main reason: With the increasing number and complexity of automotive functions, the load rate of traditional CAN bus (CAN2.0) is getting higher and even higher
