A Product Line of Diodes Incorporated AH49F LINEAR HALL EFFECT IC Description Pin Assignments The AH49F is a small, versatile linear Hall-effect device that is operated by the magnetic field from a permanent magnet or an electromagnet. The output voltage is set by the supply voltage and varies in proportion to the strength of the magnetic field. (Top View) (Front View) NEW PRODUCT GND The integrated circuitry features low noise output, which makes it unnecessary to use external filtering components. It also includes precision resistors to provide increased temperature stability and accuracy. The operating temperature range of these linear Hall sensors is -40°C to +105°C, appropriate for commercial, consumer, and industrial environments. 3 The AH49F is available in standard TO-92S, SC59 and U-DFN2020-6 packages. 3 OUT 2 GND 1 VCC 1 2 VCC OUT TO-92S SC59 (Top View) Features Power Consumption of 3.0mA at VCC = 5V for Energy Efficiency Single Current Sourcing Output Linear Voltage Output for Circuit Design Flexibility Low Noise Output Virtually Eliminates the Need for Filtering A Stable and Accurate Output Temperature Range: -40°C to +105°C Responds to Either Positive or Negative Gauss The Maximum Instantaneous Supply Voltage Up to 50V High ESD Rating: 6000V (Human Body Model) 600V (Machine Model) Small low profile U-DFN2020-6 and Industry Standard SC59 and TO-92S Packages Totally Lead-free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3) Notes: OUT 1 NC 2 VCC 3 6 NC 5 GND 4 NC U-DFN2020-6 Applications Position Sensing Liquid Level Sensing Weight Sensing Ferrous Metal Detector Vibration Sensing Rotary Encoder Magnetic Code Reading Motor Control Current Sensing 1.

For TO-92S and U-DFN2020-6 packages, if a South magnetic pole approaches the part marking surface (the side with part marking ID) of the Hall effect sensor, the circuit will drive the output voltage higher. In contrary, a North magnetic pole will drive the output voltage lower. The variations of voltage level up or down from the quiescent output voltage (the null voltage) are symmetrical and is proportional to the magnetic flux density. In the SC59 the die is placed underneath the lead frame and therefore when a magnet pole approaches the SC59 part marking surface, the direction of the magnetic field in to the die is reversed compared to TO-92S. This results in a reverse response to the magnetic flux density in SC59 package compared with TO-92S and U-DFN2020-6 packages. (i.e. if the reverse magnetic pole approaches the part marking surface of SC59, the output is the same as TO-92S package.) The largest magnetic sensitivity is obtained with a supply voltage of 8V, but at the cost of increased supply current and a slight loss of output symmetry. So, it is not recommended to work in such condition unless the output voltage magnitude is a main issue. The output signal can be capacitively coupled to a next-level amplifier for further amplifying if the changing frequency of the magnetic field is high.
