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 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
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.
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.
