AH337
General Description
AH337 is an switched Hall-Effect IC which is for
contactless switching applications. The device
includes an on-chip Hall voltage generator for
magnetic sensing, an amplifier that amplifies the
Hall voltage, a schmitt trigger to provide switching
hysteresis for noise rejection, and an open-drain
output. The bandgap regulator allows a wide
operating voltage range.
If a magnetic flux density larger than threshold Bop,
DO is turned on(low). The output state is held until
a magnetic flux density reversal falls below Brp
causing DO to be turned off (high).
