Application of Hall IC in Automobile Skylight Anti-clip Motor
The sunroof anti-clip motor is driven by the motor, and there is a sensor in the motor circuit, which can start the protection circuit to cut off the motor power. When the object is clamped, the load of the motor - the glass stops moving, when the current of the motor increases to a certain set value, the protection circuit starts and the motor stops.

Application of Hall IC in Automotive Tailgate Pusher Motor
The electric push rod is an electric drive device that converts the rotary motion of the motor into a linear reciprocating motion of the push rod. The Hall controller used in the automotive tailgate electric strut is a Hall sensor consisting of a Hall switch, but the pushrod with Hall control must be matched with a dedicated controller.

Hall IC is applied in automotive electronic throttle
The electronic throttle generally adopts a linear Hall. The working principle is that the accelerator pedal is linked with the magnet. When the pedal is stepped on, the throttle linkage shaft drives the magnet to rotate. At this time, the distance between the Hall and the magnet changes, and the corresponding linear Hall output voltage changes. The value also changes. By measuring the correspondence between the output voltage value and the position of the magnet, the angular displacement data of the pedal of the throttle can be calculated. Sending the signal of the accelerator pedal to the depth and speed, this signal will be received by the control system, and then the control command will be issued to the throttle to quickly and accurately open the angle it should open. The electronic throttle control system is mainly composed of an accelerator pedal, a pedal displacement sensor, an ECU (Electronic Control Unit), a data bus, a servo motor and a throttle actuator. The displacement sensor is mounted inside the accelerator pedal to monitor the position of the accelerator pedal at any time. When it is detected that there is a change in the height position of the accelerator pedal, the information will be sent to the ECU in an instant, and the ECU performs arithmetic processing on the information and the data information transmitted from other systems, calculates a control signal, and sends it to the servo motor relay through the line, and the servo The motor drives the throttle actuator and the data bus is responsible for communication between the system ECU and other ECUs.

Hall IC is used in car odometer
The car odometer can display the mileage of the car, and it is indirectly based on the number of revolutions of the wheel. The number of wheel revolutions can be measured by Hall IC. The sensor is an important component of the odometer, and its performance plays an extremely important role in the operation of the whole circuit.
