The on-chip commutation logic consists of a decoder and state machine which together read the inputs of three Hall sensor inputs (or I/O signals from a microprocessor). The IC then outputs the correct ...

Targeting use in automotive Hall-commutated three-phase motors, the temperature- and voltage-grade A3930 and A3931three-phase BLDC (brushless-direct-current)-motor-controller ICs integrate the ...

From Allegro MicroSystems come two automotive-grade (temperature and voltage rated) three-phase BLDC motor controller ICs.
