TDK's Hall switch series products HAL 15xy are upgraded to ASIL-B

     TDK upgraded the Hall effect switch series product HAL 15xy used by Micronas for automotive and industrial applications. At present, all products are defined as SEooC ASIL-B level conforming to ISO 26262. Modules equipped with HAL 15xy can more easily meet higher safety standards in automotive applications, such as brake fluid level sensing, safety belt detection and brake light switch.

     HAL 15xy meeting AEC-Q100 provides many diagnostic functions, which can be used for ASIL A and ASIL B automotive applications. For stricter safety requirements, HAL 15xy has additional and unique power on self-test function. The customer can perform a full functional test on the signal processing path and output of the sensor before starting the standard operation to increase the diagnostic coverage.

     The HAL 15xy sensor is designed for trouble free operation in the most demanding environments, providing a wide supply voltage range from 24 V to 2.7 V. Under the ambient temperature of − 40 ° C to 150 ° C, it can reliably measure when the voltage is sudden, and has greater robustness to the voltage peak when the load dump pulse is up to 40 V. In addition, HAL 15xy series meets the high ESD level up to ± 8 kV (HBM).

     In the three wire version of open drain output with short circuit protection and the two wire version of live current source interface, customers can choose various constant switching points for temperature compensation. In addition to the small SOT23 SMD package conforming to JEDEC standards, HAL 15xy also has a TO92-UA package.
