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 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 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.
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.
