NOT RECOMMENDED FOR NEW DESIGN USE AH3774 AH175 HALL EFFECT LATCH FOR HIGH TEMPERATURE Description Pin Assignments AH175 is a single-digital-output Hall-Effect latch sensor for high temperature operation. The device includes an on-chip Hall voltage generator for magnetic sensing, an amplifier to amplify Hall voltage, and a comparator to provide switching hysteresis for noise rejection, (Front View) an open-collector output pre-driver. An internal band-gap regulator 3.OUT provides a temperature compensated supply voltage for internal 2.GND circuits and allows a wide operating supply range. 1.Vcc When the magnetic flux density (B) is larger than operate point (Bop), SIP-3 (Bulk Pack) 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) The AH175 is available in SIP-3 (Ammo Pack), SIP-3 (Bulk Pack) and 3. OUT SC59 packages. GND 2. 1.
