TLE4941HALA1

The TLE4941HALA1 is a magnetic sensor switch designed for automotive applications. It features a Hall-effect transistor operating in discrete, open-collector mode for switching high-current loads. The device has a low-profile, flat-top design and is suitable for applications where space is limited. The TLE4941HALA1 is used in automotive electronics, automotive HVAC systems, industrial automation, and consumer/appliance applications.

The TLE4941HALA1 is a solid-state switch that uses a Hall-effect transistor to detect magnetic fields and activate its output. The Hall-effect transistor works by detecting the presence of a magnetic field and then turning on or off its output depending on the polarity and strength of the magnetic field. When a strong enough magnetic field is detected, the transistor switches on its output and a current is allowed to flow. The opposite happens when the magnetic field fades and the device turns off its output, effectively breaking the current flow.

The TLE4941HALA1 has a low profile and is capable of handling high currents without having to sacrifice physical size. This makes it ideal for applications where space is limited, such as automotive electronics and consumer appliances. The device is built to withstand vibration and thermal shock, making it suitable for automotive and industrial automation applications. It also comes with various protection features, such as reverse battery protection and over-temperature protection, to ensure reliable operation even in harsh environments.

The TLE4941HALA1 is a versatile device that is capable of detecting a wide range of magnetic fields from 0.35 mT up to 4 mT in either direction. The device has a wide operating temperature range from -40°C to +85°C with an accuracy of ±5%. The output current of the device is 5 mA maximum, and the operating voltage range is from 4 V to 12 V.

In summary, the TLE4941HALA1 is a versatile solid-state switch that can be used in a variety of applications, including automotive electronics, HVAC systems, industrial automation, and consumer/appliance applications. It is capable of detecting a wide range of magnetic fields and provides reliable operation even in harsh environments. The device is also very compact, making it ideal for applications where space is limited.
