Rotary Position Hall IC
A monolithic programmable Triaxis Hall IC, the MLX90316 from Melexis Microelectronic Integrated Systems, Concord, NH, is designed for absolute noncontacting 360° rotary position sensors. The device, which features Sentron's integrated magneto-concentrator technology, measures both components of flux density parallel to the IC surface. A diametrically magnetized magnet rotating above the sensor induces sine and cosine signals and a smart DSP core computes high-accuracy angular information from the raw signals.
