NOTES: 1. Operate and release points will vary with supply voltage.
2. BOPx = operate point (output turns ON); BRPx = release point (output turns OFF).
3. Typical Data is at TA = +25°C and VDD = 2.75 V and is for design information only.

NOTES: 1. As used here, negative flux densities are defined as less than zero (algebraic convention) and -50 G is less than +10 G.
2. Typical Data is at TA = +25°C and VDD = 2.75 V and is for design information only.
