Safety-compliant BLDC sensor, in distribution
The Infineon TLE5501 XENSIV magnetic 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 device is also the first to achieve the highest automotive functional safety grade for angle sensors, ASIL D, with just a single sensor chip.
The TLE5501 devices offer direct microcontroller connection through output signals of up to 0.37 volts per volt (V/V). The devices’ high output voltage allow them to be used without an additional internal amplifier, providing a low-power, low-cost solution when connected directly to the microcontroller. The sensors feature a supply current of approximately 2 mA and a magnetic field range of 20 mT to 100 mT.
The sensors also feature a discrete bridge with differential sine and cosine output. While both sensors 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.
Besides being ideal for automotive safety applications, the TLE5501 XENSIV can also be used in industrial applications including robotics, gimbals and automation.
