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.

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.

digital camera flash trigger

In the digital camera flash trigger circuit, the resistor plays the role of current limiting and protection. At the moment of triggering, a large current will be generated in the circuit. The current-limiting resistor can effectively limit the size of the current and prevent excessive current from damaging the flash tube, transistors and other components in the trigger circuit. At the same time, the resistor participates in the formation and transmission of the trigger pulse

Smart door lock motor drive

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.
