The Infineon hall effect sensor IC is designed to provide information about rotational speed, direction of rotation, assembly position and limit air gap to modern vehicle dynamics control systems and ABS. The output has been designed as a two wire current interface based on a pulse width modulation principle. The sensor operates without external components and combines a fast power-up time with a low cut-off frequency. Excellent accuracy and sensitivity is specified for harsh automotive requirements as a wide temperature range, high ESD robustness and high EMC resilience.
