June 2, 2026 /SemiMedia/ — TDK has added the HAL 3025 to its Micronas fast Hall position sensor family, targeting next-generation x-by-wire motor control systems that require high-speed angle measurement and functional safety capability.
The new single-die sensor follows the HAL 3020 and HAL 3021 devices and is assessed for ISO 26262 ASIL D requirements. Samples are already available, with production planned for the second quarter of 2026.
HAL 3025 measures full 360-degree rotational angle by evaluating the vertical magnetic field component using TDK-Micronas SixSense technology. The approach supports suppression of external DC and AC magnetic stray fields in line with ISO 11452-8, allowing the device to operate near power electronics in compact motor designs.
TDK said the sensor eliminates the need for costly magnetic shielding or oversized target magnets. A simple two-pole ferrite magnet in an end-of-shaft configuration is sufficient, giving engineers more freedom in motor layout design while reducing total system cost.
The device is designed as SEooC ASIL D ready and uses a single-die failsafe architecture. Compared with multi-die approaches, this can reduce system complexity, bill of materials and board space.
HAL 3025 also integrates on-chip safety monitoring functions to improve diagnostic coverage and reduce the amount of external supervision required from the electronic control unit. This supports earlier fault detection, simpler diagnostics and safer startup and runtime operation.
For high-performance motor control, the sensor supports rotational speeds of up to 60,000 rpm. Its analog signal path provides fast response time and high output bandwidth, which are important for electric powertrains and safety-critical actuators.
Using the device’s differential or single-ended sine and cosine analog outputs, external microcontrollers or ECUs can calculate absolute angular position with high resolution.
The sensor’s non-volatile memory allows programming of key signal-path parameters, including sine/cosine gain, offset, orthogonality, zero angle and magnetic signal bandwidth, through the output pin. This removes the need for additional programming pins and supports end-of-line calibration.
HAL 3025 operates across a junction temperature range from -40°C to +170°C and is offered in a compact SOIC8 SMD package. Its pin-compatible footprint with HAL 3020 and HAL 3021 enables existing designs to upgrade to a higher safety level for future x-by-wire motor architectures.
