Components & parts from TDK-Micronas

IC HALL EFFECT SENSOR SOIC8 The TDK-Micronas HAL 302x 2D sensor family is ideal for fast angle detection that meets the need for stray-field-robust motor position sensing with an ISO 26262-compliant development. HAL 302x series sensors feature differential or single-ended sine and cosine analog outputs with integrated wire-break detection. The angle of rotation of a magnet can be calculated using an external A/D converter and a microcontroller/ECU. The HAL 302x family consists of two members. Both members measure vertical magnetic field components (BZ) based on Hall effect technology. The special feature of the HAL 3021 is that the sensor offers greater robustness against static and dynamic mechanical tolerances. Due to the arrangement of the Hall plates, both sensors are capable of suppressing external magnetic interference fields. To measure the absolute angular position, only a simple two-pole magnet in an end-of-shaft configuration is required. The magnet can be positioned above or below the sensor. Key properties such as gain, offset, (absolute) zero angle, orthogonality of the sine and cosine signals, and bandwidth can be adjusted via the integrated signal path by programming the HAL 302x's non-volatile memory. The component is defined as a Safety Element out of Context (SEooC) ASIL C ready according to ISO 26262:2018. The HAL 302x includes integrated diagnostic functions, such as overvoltage and undervoltage detection and wire-break monitoring during normal operation. The sensor family is designed for automotive and industrial applications. It operates in an ambient temperature range of -40°C to +150°C. The sensors are available in SOIC8 SMD packages.
