Product application
In the LCD TV backlight drive circuit, resistors play a key role. The sampling resistor monitors the backlight current in real time, converts the current information into a voltage signal and feeds it back to the driver chip. The chip adjusts the output accordingly to achieve stable control of the backlight brightness. The voltage dividing resistor provides a suitable reference voltage for the drive circuit to ensure that the circuit
In the Bluetooth speaker volume control circuit, the potentiometer is used as an adjustable resistor to adjust the audio signal amplitude by changing the resistance of the access circuit. Turn the potentiometer knob, and its moving piece slides on the resistor body, changing the ratio of the upper and lower voltage dividing resistors, thereby changing the voltage of the output audio signal and achieving stepless adjustment of the volume. same
In the smart door lock motor drive circuit, the braking resistor absorbs the motor's counter electromotive force. When the motor is powered off or reversed, a back electromotive force will be generated, which may damage the drive circuit components. The braking resistor converts the back electromotive force into heat energy and consumes it to protect the safety of the circuit. The current detection resistor monitors the motor current in real time and feeds it back to the control core.
In the smart watch heart rate monitoring module, the resistor provides a stable working environment for the sensor. The bias resistor provides the appropriate bias voltage for the photoelectric sensor, so that the sensor can accurately detect changes in light intensity in the blood, thereby accurately calculating the heart rate. Resistors are also used in signal conditioning circuits to process weak signals output by sensors.
