AH266 is an integrated Hall sensor with output drivers designed
for electronic commutation of brush-less DC motor applications.
The device includes an on-chip Hall voltage generator for
magnetic sensing, a comparator that amplifies the Hall voltage, a
Schmitt trigger to provide switching hysteresis for noise rejection,
and complementary Darlington open-collector drivers for sinking
large current loads. An internal band-gap regulator is used to
provide temperature compensated supply voltage for internal
circuits and allows a wide operating supply range.
If a magnetic flux density (B) is larger than operation point (Bop),
DO will turn on (low) and DOB will turn off (high). The output state
is latched prior to reaching release point (Brp). If B< Brp, DO will
turn off and DOB will turn on. AH266 is rated for operation over
o
o
temperature range from -20 C to 85 C and voltage range from
4V to 28V. The devices are available in low cost die forms or
rugged 4 pin SIP packages.
