Application Field

The ATS643LSH-I2 has several application specific features such as temperature compensations, zero shift, over temperature protection, and a high accuracy for closed loop control in automotive engine control systems. This sensor can be used in a variety of applications including cam and crank shaft position sensing, automotive transmission control, timing control, position sensing, motor control, and current monitoring. The wide temperature range allows this sensor to be used in a variety of automotive applications which require a temperature range from -40°C to 150°C.

Working Principle

The ATS643LSH-I2 operates on the principle of a Hall effect sensor. As a magnetic field is introduced near this sensor, the electrons spread evenly throughout the material, creating an electric field that is perpendicular to both the current and the magnetic field. This results in a voltage across the material which is proportional to the strength of the magnetic field, which is then processed by the integrating amplifier located on the sensor.

The ATS643LSH-I2 has several features to enhance accuracy and sensitivity such as temperature compensation, zero shift, over temperature protection, enhanced linearity, and a high precision integrated amplifier. The temperature compensations feature ensures the accuracy of the output voltage over a wide temperature range. The zero shift feature minimizes temperature related drift and the over temperature protection shields the sensor from high temperatures. The enhanced linearity of the sensor ensures accurate measurements even at very low magnetic field values while the high precision amplifier processes the output from the sensor and makes sure it is of optimal quality.

The ATS643LSH-I2 is a versatile sensor with a small form factor and wide temperature range. It is an ideal sensor for automotive engine control applications due to its features and accuracy. With new automotive trends such as connected vehicles and autonomous driving, this sensor is an essential component for advanced sensing capabilities.
