inductiveanalogmetal

High performance off-axis inductive position sensor with differential analog SIN/COS output Features Can be used in environments where lateral space is at a premium Can sense motors with low and high pole-pair counts without losing resolution Reduces torque ripple and increases efficiency of motor control Works with motors up to 480 000rpm Easy replacement of existing AMR/GMR sensors Enabler for safety critical applications Suitable for automotive applications Benefits Flexible pcb design possible – Hollow shaft and side shaft applications Adaptable coil and sensor layout High angular accuracy (less than 1.0°) Low propagation delay Sin/Cos output Functional safety, diagnostics AEC-Q100 Grade 0 qualified Product parameters Resolution: 0.3° elctrical INL Interfaces: I2C Output: Differential analog SIN/COS Max. Speed [rpm]: 100000 (for 4-pole-pair) Overvoltage Protection: Yes Redundant: No Package: TSSOP-14 Automotive Qualified: Yes General Description The inductive motor control position sensor detects the electrical position within one pole-pair of a rotating shaft and can be used for the motor commutation of a brushless DC (BLDC) motor. Based on the inductive sensor technology, this family measures the coupling between an excitation coil (TX) and two receiver coils (RX) via a rotating target. The coils are executed as printed circuit coils and the rotating target is a simple punched metal part.
