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 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
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 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.
