Linear Hall Sensor GX603 in Low-speed Electric Vehicles

Linear Hall sensors play an important role in the safe driving of low-speed electric vehicles. Generally, electric vehicles use brushless and toothless motors, which need to have the function of automatically changing the direction of the current in order to realize the continuous rotation of the motor.

The Hall element can sense the position of the rotor relative to the magnetic field, and input the signal of the sensed magnetic pole into the controller, and then the controller outputs the current, so as to complete the phase change of the brushless motor. The Hall element enables the controller to change the current direction at the proper time, so the control signal is transmitted in the Hall wire of the electric vehicle.

GX603 is a small, multi-functional and economical linear Hall sensor. The principle of operation is that when a magnetic field is input, the output and input are proportional to the change in voltage, and the magnitude of the static output voltage is set by the supply voltage. The sensor features low noise output without external filtering. Electrical components can be connected without buffering. Precision resistors are also included to provide better temperature stability and accuracy.

The chip has a quiescent output voltage of 50% of the supply voltage and a sensitivity of up to 3.25mV/Gs. The operating temperature range of -40°C to 150°C makes it suitable for use in consumer electronics, industrial and medical environments. They are available in TO92S and SOT23-3L packages and are RoHS compliant. Please feel free to contact us at service_jesseli@gxschip.com.
