NOT RECOMMENDED FOR NEW DESIGN USE AH3377 AH337 SINGLE PHASE HALL EFFECT SWITCH Description Pin Assignments AH337 is a unipolar Hall-Effect sensor for contactless switching applications. The device includes an on-chip Hall voltage generator (Top View) for magnetic sensing, an amplifier that amplifies the Hall voltage, a 3. OUT Schmitt trigger to provide switching hysteresis for noise rejection, and 2. GND an open-collector output. The band-gap regulator allows a wide Vdd 1. operating voltage range. SIP-3 SIP-3 (Bulk Pack) When the magnetic flux density (B) is larger than operate point (Bop), output is switched on (OUT pin is pulled low). The output state is held on until a magnetic flux density falls below Brp. When B is less than (Top View) Brp, the output is switched off 3. OUT GND 2. The AH337 is available in SIP-3 (Ammo Pack), SIP-3 (Bulk Pack) and 1. Vdd SC59 packages. SC59 Applications Features VCD/DVD Loader, CD/DVD ROM Unipolar Hall-Effect Sensor Cover Detector 4.2V to 28V DC Operating Voltage Speed Measurement Temperature Compensation Home Appliances Open Drain Pre-Driver Home Safety 25mA Maximum Output Sink Current Operating Temperature: -40C to +125C SIP-3 (Ammo Pack), SIP-3 (Bulk Pack) and SC59 Packages (SC59 Is Commonly Known as SOT23 in Asia) Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. Green Device (Note 3) Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant. 2.
