Overview
Data Sheet BIPOLAR HALL-EFFECT POSITION SENSORS AH41 General Description The AH41 is an integrated Hall-effect latched sensor designed for electronic commutation of brushless DC motor applications.
The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifiers the Hall voltage, and a Schmitt to provide switching hysteresis for noise rejection and open-collector output.
An internal bandgap regulator is used to provide temperature 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 OFF.
This IC is available in TO-92S-3 package.
Features • On-chip Hall Sensor • Wide Operating Voltage Range: 4V to 24V • Internal Bandgap Regulator for Temperature Compensation • Maximum Output Sink Current: 50mA • Low Profile TO-92S-3 • Operating Temperature: -40˚C to 150˚C • ESD Rating: 2000V (Human Body Model) 300V (Machine Model) Application • Brushless DC Motor Nov 2010 Rev.
