ATS137
SINGLE HALL EFFECT SWITCH
General Description
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.
Applications
• VCD/DVD Loader, CD/DVD ROM
• Cover Detector
• Speed Measurement
• Home Appliances
• Home Safety

SINGLE HALL EFFECT SWITCH
Application Information
Operating principle:
ATS137 is a three-pin Hall Effect switch IC which can turn magnetic flux variety to digital output signal. In other words, it is an interface
from magnetic system to an electrical one by Hall effect. The illustrations are shown in Fig.1.
