Description
AH337 is an unipolar Hall-Effect sensor 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-collector
output. The band-gap regulator allows a wide operating
voltage 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 falls
below Brp. When B is less than Brp, the output is switched
off.
The AH337 is available in SIP-3L and SC59 packages.
