General Description
The MT1102 family, produced with CMOS technology, The Hall IC internally includes an on-chip Hall
voltage generator, a voltage regulator for operation with supply voltages of 3.5 to 24V, temperature
compensation circuitry, small-signal amplifier, Hall sensor with dynamic offset cancellation system,
Schmitt trigger and an open-drain output.
They are designed to respond to a single pole: North (AT) or South (A, BT and ET). While the magnetic
flux density(B) is larger than operate point (Bop), the output will be turned on (Low), while the magnetic
flux density(B) is lower than release point (Brp), then turn off (High).
The MT1102 family provides a variety of packages to customers: SOT-23/SOT-89B for surface mount and
TO-92 flat for through-hole mount. All packages are RoHS compliant.
