www.DataSheet4U.com AS5304 / AS5306 Integrated Hall ICs for Linear and Off-Axis Rotary Motion Detection PRELIMINARY DATA SHEET 1 General Description 2 Benefits Complete system-on-chip High reliability due to non-contact sensing Suitable for the use in harsh environments Robust against external magnetic stray fields The AS5304/AS5306 are single-chip IC’s 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 multipole magnetized ring or strip and provides a quadrature incremental output with 40 pulses per pole period at speeds of up to 20 meters/sec (AS5304) or 12 meters/sec (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/rev, which is equivalent to 5120 positions/rev 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 (AS530xA) or with open drain outputs (AS530xB) . The AS5304/AS5306 are ...
