Product application
In the mobile phone charging circuit, the resistor plays the role of current limiting and protection. After the charger converts alternating current into direct current, the resistor prevents excessive current from damaging the battery and circuit components. When an internal fault in the charger causes abnormal current, a suitable resistor can limit the current in time to avoid the fault from expanding and ensure charging safety.
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 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 gamepad button circuit, the pull-down resistor is used to eliminate button jitter. When a key is pressed or released, due to mechanical structure reasons, a brief level instability will occur, that is, key jitter. The pull-down resistor stabilizes the button signal line at a low level when the button is not pressed. When the button is pressed, the signal line is pulled to a high level.
