This sensor family consists of various members. All devices can measure a 360° angular range as well as linear movements. HAL/R 3900 and HAL/C/R 3930 support the option for 3D position detection. Depending on the device, it is possible to transmit temperature-compensated values of Bx, By, Bz or up to two calculated angles. The HAL 3980 is also capable of transmitting the angular speed. All devices offer setpoint linearization with either 33 equidistant distributed setpoints or 17 variable setpoints. The sensors measure the position of a magnet based on 3D HAL® technology from TDK-Micronas. The devices are able to suppress external magnetic stray fields by using an array of Hall plates. Only a simple two-pole magnet is required to measure a rotation angle. Off-axis measurements are also possible. The sensors are defined as SEooC (Safety Element out of Context) ASIL B ready according to ISO 26262. Major characteristics like gain and offset, reference position, etc. can be adjusted to the magnetic circuitry by programming the non-volatile memory. The devices are designed for operation in an ambient temperature range of -40 °C up to 150 °C. The HAL 39xy devices are available in a very small eight-pin SOIC8 package. The HAC 39xy devices are available in a three-pin leaded TO92UF package. This package integrates up to two capacitors (max. 330 nF) together with the sensor chip. With the integrated capacitors, HAC 39xy meets stringent ESD (system level) and EMC requirements and eliminates the need for a PCB, thus reducing the total system size and cost. The HAR 39xy devices are available in a small sixteen-pin SSOP16 package with full redundancy. Each sensor contains two independent dies placed upon each other that are mechanically separated and electrically insulated. The two dies measure almost the same magnetic field, therefore ensuring synchronous output signalst.
