General Description
ATS278 is an integrated Hall sensor with two output
drivers and rotor speed output, typically designed
for electronic commutation of two-phase brush-less
DC fan applications.
On-chip Hall sensor will generate Hall voltage due
to magnetics sensing. The amplifier will amplify the
Hall voltage. The Schmitt trigger determines
switching hysteresis and then control internal
driver’s on/off to sink load current. Meanwhile, An
internal bandgap regulator is used to provide stable
bais due to temperature-compensation. FG pin will
provide switching frequency of driver. Major feature
is to minimize the external components by
building-in FG output transistor.
If a magnetic flux density larger than threshold Bop,
DO is turned on (low) and DOB is turned off (high).
The output state is held until a magnetic flux density
reversal falls below Brp causing DO to be turned off
and DOB turned on.
