Key Features

  • on-chip transient protection, and a Zener clamp to protect against overvoltage conditions on the supply line. The output currents of the A1141 and A1143 switch HIGH in the presence of a south polarity magnetic field of sufficient strength; and switch LOW otherwise, including when there is no significant magnetic field present. The A1140 and A1142 have inverted output current levels: switching LOW in the presence of a south polarity magnetic field of sufficient strength, and HIGH otherwise. The devices.
