ATS137 SINGLE HALL EFFECT SWITCH General Description Features 3.5V to 20V DC Operation Voltage ATS137 is a switched Hall-Effect IC, which is for contactless switching applications. The device includes an on-chip Hall Temperature Compensation voltage generator for magnetic sensing, an amplifier that Wide Operating Voltage Range amplifies the Hall voltage, a Schmitt trigger to provide switching Open-Collector Pre-Driver hysteresis for noise rejection, and an open-collector output. The 25mA Maximum Sinking Output Current bandgap regulator allows a wide operating voltage range. Reverse Polarity Protection ATS137 is rated for operating temperature range from -20 C to Lead Free Package: SIP-3L and SC59-3L (Commonly 85C and voltage range from 3.5V to 20V. 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) Applications VCD/DVD Loader, CD/DVD ROM Cover Detector Speed Measurement Home Appliances Home Safety Typical Application Circuit 3.5V ~20V R L V cc DO ATS137 Digital Output GND ATS137 Rev. 10 1 of 12 FEBRUARY 2010 DS31045 www.diodes.com Diodes Incorporated ATS137 SINGLE HALL EFFECT SWITCH Ordering Information ATS 137 - X X - X - X Magnetic Package Packing Lead Free Characteristics P : SIP-3L L : Lead Free A : Ammo Box (Note 3) A or B (Note 5) W : SC59-3L G : Green B : Bulk (Note 4) 7 : Tape & Reel Bulk 7 Tape and Reel Ammo Box Magnetic Package Packaging Part Part Part Device Characteristics Code (Note 2) Quantity Number Quantity Number Quantity Number (Note 5) Suffix Suffix Suffix ATS137-PL-A-A P SIP-3L NA NA NA NA 4000/Box -A A ATS137-PL-A-B P SIP-3L NA NA NA NA 4000/Box -A B ATS137-PL-B-A P SIP-3L 1000 -B NA NA NA NA A ATS137-PL-B-B P SIP-3L 1000 -B NA NA NA NA B ATS137-PG-A-A P SIP-3L NA NA NA NA 4000/Box -A A ATS137-PG-A-B P SIP-3L NA NA NA NA 4000/Box -A B ATS137-PG-B-A P SIP-3L 1000 -B NA NA NA NA A ATS137-PG-B-B P SIP-3L 1000 -B NA NA NA NA B ATS137-WL-7-A W SC59-3L NA NA 3000/Tape & Reel -7 NA NA A ATS137-WG-7-A W SC59-3L NA NA 3000/Tape & Reel -7 NA NA A Notes: 1.
