General Description AS5304/AS5306 Integrated Hall ICs for Linear and Off-Axis Rotary Motion Detection The AS5304/AS5306 are single-chip ICs with integrated Hall elements for measuring linear or rotary motion using multi-pole magnetic strips or rings. This allows the usage of the AS5304/AS5306 in applications where the Sensor IC cannot be mounted at the end of a rotating device (e.g. at hollow shafts). Instead, the AS5304/AS5306 are mounted off-axis underneath a multi-pole magnetized ring or str.

General Description AS5304/AS5306 Integrated Hall ICs for Linear and Off-Axis Rotary Motion Detection The AS5304/AS5306 are single-chip ICs with integrated Hall elements for measuring linear or rotary motion using multi-pole magnetic strips or rings. This allows the usage of the AS5304/AS5306 in applications where the Sensor IC cannot be mounted at the end of a rotating device (e.g. at hollow shafts). Instead, the AS5304/AS5306 are mounted off-axis underneath a multi-pole magnetized ring or strip and provides a quadrature incremental output with 40 pulses per pole period at speeds of up to 20 meters/second (AS5304) or 12 meters/second (AS5306). A single index pulse is generated once for every pole pair at the Index output. Using, for example, a 32pole-pair magnetic ring, the AS5304/AS5306 can provide a resolution of 1280 pulses/revolution, which is equivalent to 5120 positions/revolution or 12.3bit. The maximum speed at this configuration is 9375 rpm. The pole pair length is 4mm (2mm north pole / 2mm south pole) for the AS5304, and 2.4mm (1.2mm north pole / 1.2mm south pole) for the AS5306. The chip accepts a magnetic field strength down to 5mT (peak). Both chips are available with push-pull outputs (AS5304A) or with open drain outputs (AS530xB). The AS5304/AS5306 are available in a small 20-pin TSSOP package and specified for an operating ambient temperature of -40°C to 125°C.
