ATS137 SINGLE HALL EFFECT SWITCH Features • • • • • • • • • 3.5V to 20V DC Operation Voltage Temperature Compensation Wide Operating Voltage Range Open-Collector Pre-Driver 25mA Maximum Sinking Output Current Reverse Polarity Protection Lead Free Package: SIP-3L and SC59-3L (Commonly known as SOT23 in Asia) SIP-3L and SC59-3L: Available in “Green” Molding Compound (No Br, Sb) Lead Free Finish / RoHS Compliant (Note 1) 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.
