Product application
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 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 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.
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
