TDK HAL3725DJ-A

The HAL 37xy family comprises the second generation of sensors using the proprietary Micronas 3D HAL technology. This new family has several members. HAL 372x provides a linear, ratiometric analog output signal with integrated wire- break detection working with pull- up or pull- down resistors. Compared to HAL 372x, the HAL 371x is splitting the 360° measurement range either into four repetitive 90° (MOD 90°) or three 120° (MOD 120°) segments. HAL 373x features digital output formats like PWM and SENT (according to SAE- J2716 release 2010). The digital output format is customer programmable. The PWM output is configurable with frequencies between 0.2kHz and 2kHz with up to 12 bit resolution. Conventional planar Hall technology is only sensitive to the magnetic field orthogonal to the chip surface. In addition to the orthogonal magnetic field, HAL 37xy is also sensitive for magnetic fields applied in parallel to the chip surface. This is possible by integrating vertical Hall plates into the standard CMOS process. The sensor cell can measure three magnetic- field components BX, BY, and BZ. This enables a new set of applications for position detection, like wide distance, angle or through- shaft angular measurements.
