2, the Driver generally refers to the Device driver (Device Driver), equivalent to the interface of the hardware, the operating system can only control the work of the hardware device through this interfaceIf the driver of a device is not installed correctly, it will not work normally, and the pre-drive is to add a drive when the drive circuit alone cannot complete the task.
3, the driver chip generally plays a driving role, well, that is, the input weak signal is amplified into a strong enough, suitable for the strong signal of external equipment, the need for ampere-level drive current is generally to drive the motor or power electronic equipment and so on.
4, the automotive chip is a large number of microelectronic components (transistors, resistors, capacitors, etc.) formed integrated circuits on a plastic base, to make a chip. Mainly refers to the placeProcessor and controller chip. China has become the world's largest automotive market, the trend of electrification and intelligence has promoted the number of automotive chips to increase significantly, and the localization of automotive chip has a scale basis.
5, the computer chip is the chip used in the computer, the computer chip is actually an electronic part, in a computer chip contains the driver chip thousands of resistors, capacitors and its driver chip he small components. There are many chips on the computer, long black strips on the memory barIs a chip, motherboard, hard disk, graphics card, etc., there are a lot of chips, CPU is also a computer chip, but driver chip he is more complex than ordinary computer chips more sophisticated.
6, the L9369 is an electronic dual-way H-bridge predriver produced by ST for electronic parking braking. The L9369 is mainly aimed at electronic parking brake applications, and its internal structure is a dual H-bridge driver, driving eight external field effect tubes, each controlling the rear wheel brake attenuator. All levels of braking can be configured by SPI separately to PWMControl mode drive with overcurrent protection while monitoring drain-source and grid-source voltages.
2, USB is a more complex communication protocol, the so-called controller will automatically be in some lower-level protocols (generally should have a microprocessor), the MCU can be controlled with USB at a higher level. The driver is mainly driven by signalThe MCU has to do low-level intervention. CH375 seems to belong to the controller interface is relatively simple, pdiusbd12 seems to belong to the drive control is more complex, but the two can not be used at the same time can only choose one of them.
3, driver chip: Driver chip is responsible for controlling the brightness and color of the LCD screen, so that the display can display a clear, bright image. Capacitor: A capacitor is a component that stores charge, which can output current smoothly to ensure the stability and reliability of the display. Resistance: Resistance is a device that regulates the current, which can limit the size of the current and make the display work in different waysStable current output can be maintained in the state.
4, the driver and the controller are different driver functions, the controller is specialized in sending pulse signals to the driver. Stepper motor controller and driver different role Stepper motor controller is a kind of electronic products that can send an average pulse signal, and the signal it sends into the stepper motor driver will be converted by the driver into the strong current signal required by the stepper motor to drive the stepper motor operation.
5, stepper motor and ordinary motor is not controlled by signal, stepper motor generally has more than two windings, power state, stepThe dynamic chip can control a single or multiple leds. There are also driver chips that can control multiple leds.
Its working principle is to convert the input current into the current and voltage suitable for LED lamp work. Specifically, the LED driver chip is usually composed of two parts: the power supply part and the control part. The power supply part is responsible for converting the input voltage into the voltage and current suitable for the work of the LED lamp, while the control part is responsible for adjusting the size of the current according to the need to control the brightness of the LED lamp.
Working principle The core function of the LED driver chip is to control the brightness of the LED lamp.It regulates the output current through the internal control circuit, so that the LED lamp works at different brightness. This process ensures the stability and efficiency of LED lights. The circuit design of the LED driver chip usually includes the following key parts: - Input voltage control: This part is responsible for stabilizing the input voltage to ensure that the driver chip can operate normally.
Its working principle is to use the control circuit inside the circuit to control the size of the output current, so that the LED lamp produces different brightness output. The circuit design of the LED driver chip is generally composed of the following parts: Input voltage controlSystem: This part is responsible for stabilizing the input voltage and ensuring that the driver chip can work normally. Control circuit: This part is responsible for controlling the brightness of the LED lamp, and the output current can be adjusted according to the demand.
