Diodes Incorporated AH337
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.| Part No. | AH337 |

DESCRIPTION
Pin Assignments 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. (Top View) SIP-3L 3. OUT 2. GND 1. Vdd (Top View) GND 2. SC59 3. OUT 1.
