Mouser Electronics stocks the TLE5501 XENSIV magnetic sensor from Infineon Technologies. Infineon’s first magnetic sensors based on tunnel magneto resistance technology, the TLE5501 sensors are ideal for automotive brushless DC motor commutation in devices such as wipers, pumps and actuators, as well as for steering angle sensing and integration in electric motors.
The sensors are AEC-Q100-qualified for a broad range of automotive applications. The E0001 version is pin-to-pin compatible with the Infineon TLE5009 angle sensor, while the E0002 is compliant with ISO 26262 standards for increased functional safety. The E0002 is also the first to achieve the highest automotive functional safety grade for angle sensors, ASIL D, with just a single sensor chip.
The sensors offer direct microcontroller connection through powerful output signals of up to 370mV/V. Their high output voltage allows them to be used without an additional internal amplifier, providing a low-power, low-cost solution when connected directly to the microcontroller. They feature a supply current of approximately 2mA and a magnetic field range of 20 to 100mT.
The sensors also feature a discrete bridge with differential sine and cosine output. While both versions offer a typical angle error of only one degree over the entire temperature and lifetime profile, the E0002 device offers higher diagnostic coverage and redundant external angle calculation through the use of decoupled bridges.
The sensors are ideal for automotive safety applications but can also be used in industrial applications including robotics, gimbals and automation.
