AH373
INTERNAL PULL-UP HALL EFFECT LATCH
Description
AH373 is a single-digital-output Hall-Effect latch sensor with internal
pull-up resistor for high temperature operation. The device includes
an on-chip Hall voltage generator for magnetic sensing, an amplifier
to amplify Hall voltage, and a comparator to provide switching
hysteresis for noise rejection, and an output driver with a pull-up
resistor. 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) perpendicular to the package 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.
