Product application

E-book reader backlight adjustment

In the e-book reader backlight adjustment circuit, the voltage dividing resistor realizes linear adjustment of the backlight brightness. By changing the resistance ratio of the voltage dividing resistor, the voltage provided to the backlight can be adjusted, thereby changing the backlight brightness. At the same time, the resistor participates in the feedback control of the backlight drive circuit, feeding back the backlight current information to the drive core.

Bluetooth speaker volume control

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

Gamepad button circuit

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.

Laptop power management

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.
