Adding to its collection of TMR angle sensors, TDK has announced the TAD2140 type in a TO-6 package for automotive and industrial applications. The sensor provides a system-in-package solution for PCB-less applications. It includes two full TMR bridges, a dedicated ASIC for signal conditioning and integrated passive components.

The TAD2140 features an angle accuracy of ±0.2°, achieving a small angle error of only ±0.05° at room temperature. The sensors are capable of contactless sensing from 0 to 360° over a temperature range of −40 to +150°C. The sensor's fast response, high angular accuracy, and advanced compensation algorithms help with motor control applications such as BLDC motor commutation. Moreover, thanks to its small package size, the sensor is suited for applications with limited available space, such as steering motor commutation. Samples will be available from the third quarter of 2018. Start of production is planned for the third quarter of 2019.

TDK will present the new TAD2140 sensor from June 26th-28th, 2018 at the Sensor+Test exhibition in Nuremberg, Germany, at booth 204 in hall 1 and at the same time at the Sensors Expo in San Jose, California, at booth 416.

The TAD2140 comes in a new TO-6 package that integrates six capacitors and one resistor. The sensor can be welded or soldered directly onto a package lead, a connector or a terminal, eliminating the need for a PCB. By using fewer external components and lowering the number of solder joints, the long-term reliability of the overall system has improved.

The sensor can compensate any drifts of gain, offset or orthogonality as well as magnet tilt or displacement. In addition, the implemented algorithms allow higher assembly tolerances of mechanical components or increase of the system performance with existing solutions. The ASIC provides several digital outputs such as Hall emulation (UVW), encoder (ENC), pulse-width modulation (PWM), and SENT on two interfaces simultaneously. Furthermore, its various internal diagnostic features make it suitable for automotive applications where functional safety is required (ASIL B rating).
