NOTES: * Complete part number includes a prefix to identify operating temperature range (UGN or UGS) and the package suffix KA.
Magnetic switch points are specified as the difference in magnetic fields at the two Hall elements.
As used here, negative flux densities are defined as less than zero (algebraic convention).
Typical values are at T_A = 25°C and V_CC = 12 V.
