... The A1101-A1104 and A1106 Hall-effect switches include the following on a single silicon chip: voltage regulator, Hall-voltage generator, small-signal amplifier, Schmitt trigger, and NMOS output transistor. The integrated voltage regulator permits operation from 3 The extensive on-board protection circuitry makes possible a ± ...

A1101, A1102, A1103, A1104, and A1106 MAGNETIC OPERATING CHARACTERISTICS Characteristic Symbol Operate Point B Release Point B Hysteresis B 1 Magnetic flux density indicated as a negative value for north-polarity magnetic fields, and as a positive value for south-polarity magnetic fields. This so-called algebraic convention supports arithmetic comparison of north and south polarity values, where the relative strength of the field is indicated by the absolute value of B, and the sign indicates the polarity of the field (for example, a – ...
