A1140 Sensitive Two-Wire Chopper-Stabilized Unipolar Hall-Effect Switches

A1140/41/42/43 Sensitive Two-Wire Chopper-Stabilized Unipolar Hall-Effect Switches The A1140, A1141, A1142, and A1143 devices are sensitive, two-wire, unipolar, Hall effect switches that are factory-programmed at end-of-line to optimize magnetic switchpoint accuracy. These devices are produced on the Allegro MicroSystems advanced BiCMOS wafer fabrication process, which implements a patented, high-frequency, chopper-stabilization technique that achieves magnetic stability and eliminates the offse.

A1140 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 signiﬁcan
