AH375-WG-7

PART OBSOLETE - USE AH3774 AH375 SINGLE PHASE HALL EFFECT LATCH OBSOLETE – PART DISCONTINUED Description Pin Assignments The DIODES™ AH375 is an integrated Hall-Effect latched sensor designed for electronic commutation of brush-less DC motor applications. The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis for noise rejection, and open drain output. An internal band-gap regulator provides a temperature compensated supply voltage for internal circuits and allows a wide operating supply range. (Front View) 3. OUT 2. GND 1. Vdd SIP-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 reversal falls below Brp. When B is less than Brp, the output is switched off. (Top View) 3. OUT GND 2. 1.
