HAL3625 线性可编程霍尔传感器
360°可编程霍尔传感器
The HAL 36xy family is a new generation of Hall-effect sensors. Due to its advanced vertical Hall-plate technology it enables the possibility to measure magnetic fields in the chip plane. With this technology it is possible to directly measure rotation angles in a range of 0° to 360° with simple magnetic arrangements. The first member of this family is the HAL 3625.

Two on-chip vertical Hall plates measure both magnetic field components BX and BY. The direct angle information is internally calculated by the sensor using the inverse tangent function and converted into an *og output voltage. Due to the measurement method, the sensor provides an excellent drift performance over temperature and therefore a new cl* of accuracy.

The sensor provides a linear, ratiometric *og output signal with implemented wirebreak detection working with a pull-up or pull-down resistor. Major characteristics like gain and offset of X- and Y-channel, zero-angle position, phase shift between X- and Y-channel, output slope and offset and clamping levels can be adjusted to the magnetic circuit by programming the non-volatile memory.

The HAL 3625 is available in the very *all SOIC8 SMD package.
