PART OBSOLETE USE AH3774 Data Sheet BIPOLAR HALL-EFFECT POSITION SENSORS AH41 Features General Description On-chip Hall Sensor The AH41 is an integrated Hall-effect latched sensor Wide Operating Voltage Range: 4V to 24V designed for electronic commutation of brushless DC Internal Bandgap Regulator for Temperature motor applications. The device includes an on-chip Compensation Hall voltage generator for magnetic sensing, a Maximum Output Sink Current: 50mA comparator that amplifiers the Hall voltage, and a Low Profile TO-92S-3 Schmitt to provide switching hysteresis for noise Operating Temperature: -40C to 150C rejection and open-collector output. An internal ESD Rating: 2000V (Human Body Model) bandgap regulator is used to provide temperature 300V (Machine Model) compensated supply voltage for internal circuits and allows a wide operating supply range. A north pole of sufficient strength will turn the output ON. In the absence of a magnetic field, the output is Application OFF. Brushless DC Motor This IC is available in TO-92S-3 package.
