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.
