general description
ma7003 is a three-terminal hall effect sensor device with an output driver. the device isusing cmos process includes an on-chip hall voltage generator for magnetic sensing, acomparator that amplifies the hall voltage, and a schmitt trigger to provide switching hysteresisfor noise rejection, and open-drain output, and an internal temperature compensated circuits.this method reduces the offset voltage normally caused by device over molding and thermal
stress.
the output is switch with either north or south pole of sufficient strength will turn the output
on (low). the output will be turned off (high) under no magnetic field. while the magnetic flux
density (b) is larger than operate point (bop), the output will be turned on (low); the output is
latched until b is lower than release point (brp) and then turned off (high).
features
- 1.65v to 5.5v battery operation
- chopper stabilized technology
- operation with north or south pole
- high sensitivity and high stability of the magnetic switching points
- low profile sot23-3l &tsot23-3l package
