ATS278 is a single chip Hall effect latch with frequency generator (FG) output, which is designed for electronic commutation of two-phase brush-less DC fan applications.
The ATS278 is an integrated Hall sensor with two output drivers and a rotor speed output, typically designed for the electronic commutation of two-phase brushless DC fan applications. It features an on-chip Hall plate, an internal bandgap regulator for temperature compensation, and a Frequency Generation (FG) output to minimize external components.
