FUNCTIONAL BLOCK DIAGRAM
NOTES: BOP = operate point (output turns ON); BRP = release point (output turns OFF); Bhys = hysteresis (BOP - BRP).
As used here, negative flux densities are defined as less than zero (algebraic convention).
*Complete part number includes a suffix to identify operating temperature range (E or L) and package type ( LT or UA).
