ATS137 is a switched Hall-Effect IC, which is for contactless

switching applications. The device includes an on-chip Hall

voltage generator for magnetic sensing, an amplifier that

amplifies the Hall voltage, a Schmitt trigger to provide switching

hysteresis for noise rejection, and an open-collector output. The

bandgap regulator allows a wide operating voltage range.

ATS137 is rated for operating temperature range from -20°C to

85°C and voltage range from 3.5V to 20V.
