TDK unveils new 2D position sensor family for automotive
Summary
HAL 3550 and HAR 3550 are defined as safety element out of context (SEooC) and are ASIL C ready, making them suitable for integration into automotive safety-related systems up to ASIL D. HAL 3550 and HAR 3550 are high-resolution position sensors engineered for precise position measurements, featuring a linear, ratiometric analog output with passive wire-break detection, as well as configurable PWM or SENT outputs. In addition, HAL/HAR 3550 offers a switch output (open-drain), derived from calculated position information or other sources along the signal path, such as temperature or magnetic-field amplitude. A simple, low-cost two-pole ferrite magnet is sufficient for rotation angle measurements, ideally positioned in an end-of-shaft configuration. Key characteristics such as gain, offset, and reference position can be tailored to the magnetic circuitry via programmable non-volatile memory. ** Any mention of target applications for TDK Corporation products are made without a claim for fit for purpose as this has to be checked at system level.
