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.

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.

Application Information (Continued)
Vo will turn on (low) if the S magnetic flux larger than the operation point (Bop), and turns off whenever the magnetic flux is removed and
lower than the release point (Brp). The related waveforms are shown in Fig.3.

The major applications are for contactless switching and shown as follows:
•
VCD/DVD loader, CD/DVD ROM: Detect if the tray is opened or closed.
•
Cover detector (open/close): Cellular phone cover detector, refrigerator door detector, microwave oven door sensor, etc.
•
Home safety: instead of reed relay to detect the situation of door/window.
•
Due to contactless and without mechanical contact point, its reliability and life cycle are much longer than reed relay. In
addition, its switching speed is much faster than mechanical devices.
