Description
AH375 is an integrated Hall-Effect latched sensor 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, and a Schmitt trigger to provide switching
hysteresis for noise rejection, and open drain output. An
internal band-gap regulator provides a temperature
compensated supply voltage for internal circuits and allows a
wide operating supply range.
When the magnetic flux density (B) is larger than operate
point (Bop), output is switched on (OUT pin is pulled low).
The output state is held on until a magnetic flux density
reversal falls below Brp. When B is less than Brp, the output
is switched off.
The AH375 is available in SIP-3L and SC59 packages.
