Description
MXT276 integrated Hall sensor and output drive circuit, mainly used in brushless DC fan of the electrical conversion. The IC integrates a regulated circuit, protection diodes, Hall sensors, operational amplifiers, comparators and a pair of complementary open collector outputs (DO, DOB). When the magnetic flux density (B) is greater than the operating point (BOP), DO is turned on (low) and DOB is turned off (high). The state of the two output pins will be maintained until B is below the release point (BRP), and DO and DOB will change their respective output states.
