General Description

ATS137 is an 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.
