Product application
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.
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 notebook computer power management, resistors are used for voltage division and signal conditioning. Through a combination of resistors with different resistance values, the power supply output voltage can be accurately adjusted to meet the needs of different hardware such as motherboards, graphics cards, and hard drives. In the power feedback circuit, resistors participate in building a voltage dividing network to feed back the output voltage change information to the power supply.
In the wireless headset charging box, resistors play an important role. The pull-up resistor can stabilize the charging signal, avoid false triggering caused by signal interference, and ensure that the charging box accurately recognizes the earphones and starts charging. In the charging circuit, the resistor plays a current limiting role to prevent excessive charging current from damaging the headphone battery and circuit. At the same time, the resistance
