NOTES: Negative current is defined as coming out of (sourcing) the output.
BOP = magnetic operate point (output turns ON); BRP = magnetic release point (output turns OFF).
As used here, negative flux densities are defined as less than zero (algebraic convention).
Typical values are at TA = +25°C and VCC = 12 V.
* Fault condition. Device is shut down and operation is not possible.
