AH375 Datasheet | Diodes Incorporated

SINGLE PHASE HALL EFFECT LATCH Description Pin Assignments AH375 is an integrated Hall-Effect latched sensor designed for electronic mutation of brush-less DC motor applications. The device includes an on-chip Hall voltage generator for magnetic sensing, a parator 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 pensated supply voltage for internal circuits and allows a wide operating supply 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 reversal 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.
