H276Q
COMPLEMENTARY OUTPUT HALL EFFECT LATCH
 
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
DO, DOB 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.
