SA276 Datasheet, PDF (3/4 Pages) Silan Microelectronics Joint-stock – BRUSHLESS DCFAN DRIVER WITH ONCHIP HALL SENSOR

SA276
While the magnetic flux density B is larger than operate point Bop, DO will turn on and output low potential,
DOB will turn off and output high potential. Each output is latched until the magnetic flux density B is lower than
release point Brp, and then DO; DOB transfer each state.
