ATS277 Overview
ATS276/277 are integrated Hall sensors with output drivers, mainly designed for electronic mutation of brush-less DC Fan. This IC internally includes the regulator, protecting diode, Hall plate, amplifier, parator, and a pair of plementary open-collector outputs (DO, DOB). While the magnetic flux density (B) is larger than operate point (Bop), DO will turn on (low), and meanwhile DOB will turn off (high).
