Programmable direct angle Hall Sensors HAL 36xy

The HAL 36xy family is a new generation of Hall 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 B-x and B-y. The direct angle information is calculated
by the internal signal processor and converted in an analog
output voltage. Due to the measurement method, the sensor
provides an excellent drift performance over temperature and
therefore a new class of accuracy.
The sensor provides a linear, ratiometric analog output signal
with implemented wire-break 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 small SOIC8 SMD package.
