Description:

Sensitive Two-Wire Chopper-Stabilized Unipolar Hall Effect Switches

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

Applications

* the A1140-43 family of devices are utilized to sense: seat track position, seat belt buckle presence, hood/trunk latching, and shift selector position. Two-wire unipolar switches are particularly advantageous in price-sensitive applications, because they require one less wire than the more traditio
