manufacturer: description:ah276 are integrated hall sensors with output drivers, mainly designed for electronic commutation of brush-less dc fan. this ic internally includes the regulator, protecting diode, hall plate, amplifier, comparator, and a pair of complementary 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). each output is latched until b is lower than release point (brp), and then dodob transfer each state. for dc fan application, sometimes need to test power reverse connection condition. internal diode only protects chip-side but not for coil-side. if necessary, add one external diode to block the reverse current from coil-side. |
