TDK-Micronas HAL 302x Hall-Effect Position Sensors
TDK-Micronas HAL 302x Hall-Effect Position Sensors are ISO 26262-compliant, optimized sensors for high-speed, low-latency motor position applications. The HAL 302x sensor family includes the HAL 3020 and HAL 3021 with differential and single-ended sine and cosine analog outputs for standard angle calculation by an external microcontroller. The HAL 3020 is suitable for applications like electric pumps or electric valves and can be combined with TDK's Micronas embedded motor controller portfolio for more precise and safe motor control. The HAL 3021 sensor is ideal for demanding high-speed sensing applications like e-motors, electric power steering, electric brake boosters, and electromechanical braking (EMB).
These sensors can measure a full 360° rotational angle by evaluating vertical magnetic-filed components. Where the HAL 3020 uses an array of three horizontal Hall plates, the HAL 3021 uses six, and both sensors can suppress external DC and AC magnetic stray fields. TDK-Micronas HAL 302x Hall-Effect Position Sensors operate in a -40°C to +170°C temperature range and are available in a small 8-pin SOIC8 SMD package.
