Bipolar Hall-Effect Digital Position Sensor ICs: 005888 SS40F, SS40AF Issue 4 Datasheet FEATURES Small, flat TO-92-style package size allows for a compact PC board layout Current consumption of only 5 mA max at 4.5 Vdc for energy efficiency Sensitive, bipolar magnetics respond to alternating North and South poles, making these products suited for speed sensing and RPM measurement High speed: operates from 0 kHz to over 100 kHz Built-in pull-up resistor can easily interface with common electronic circuits without adding external components, helping to reduce total system cost RoHS-compliant materials meet Directive 2002/95/EC DESCRIPTION These small and versatile digital Hall-effect devices are POTENTIAL APPLICATIONS operated by the magnetic field from a permanent magnet or Commercial: Door or lid closure detection in appliances, an electromagnet, and are designed to respond to alternating speed and RPM (revolutions per minute) sensing in fitness North and South poles. The built-in regulator provides equipment, damper or valve position control in HVAC enhanced stability of operation from over a 4.5 Vdc to 24 (heating, ventilation, and air conditioning) equipment, flow- Vdc supply voltage range, and internal circuitry is designed rate sensing in appliances and water softeners, printer head to prevent sensor damage in case the supply voltage polarity position sensing is accidentally reversed. The open-collector sinking output Industrial: Flow rate sensing in industrial processes, robotic voltage is easily interfaced with a wide variety of electronic control (cylinder position monitoring), float-based fluid level circuits. Both products are designed for high volume sensing applications. The SS40F is factory tested at 25C 77F and Transportation: Brushless dc motor commutation, the SS40AF is factory tested at both 25C 77F and 125C electronic window lift, anti-pinch power window systems, 257F . These products are available in a flat TO-92-style vehicle convertible roof position package with straight leads in bulk packaging.
