null 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.
