AH337-WG-7

PART OBSOLETE USE AH3377 AH337 SINGLE PHASE HALL EFFECT SWITCH Description Pin Assignments AH337 is a unipolar Hall-Effect sensor for contactless switching applications. The device includes an on-chip Hall voltage generator (Top View) OBSOLETE – PART DISCONTINUED for magnetic sensing, an amplifier that amplifies the Hall voltage, a 3. OUT Schmitt trigger to provide switching hysteresis for noise rejection, and 2. GND an open-collector output. The band-gap regulator allows a wide 1. Vdd operating voltage range. SIP-3SIP-3 (Bulk Pack) 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 (Top View) Brp, the output is switched off. 3. OUT GND 2. The AH337 is available in SIP-3 (Ammo Pack), SIP-3 (Bulk Pack) and SC59 packages. 1.
