Скачать или смотреть Designing with position sensors: Automotive door handles

Learn how AMR angle sensors, Hall-effect sensors, capacitive sensors and inductive sensors are used to simplify controls in automotive door handle systems. The TMAG6180-Q1 device provides contact-free angle measurements for control of deployable door handles, while the TMAG5131-Q1 provides door open/close detection and the FDC1004-Q1 provides hand proximity/soft-touch detection. The LDC3114-Q1 can also be implemented for inductive touch button functionality.
