1 / 19 page AH8500 Document number: DS37511 Rev. 1 - 2 1 of 19 www.diodes.com February 2015 © Diodes Incorporated AH8500 LOW POWER/MICROPOWER LINEAR HALL EFFECT SENSOR Description The AH8500 is a low power/micropower linear Hall effect sensor with an 8-bit output resolution. The output voltage is ratiometric to the supply voltage and proportional to the magnetic flux density perpendicular to the part marking surface. The output null voltage is at half the supply voltage. AH8500 has a typical sensitivity of 2.1mV/G and 3.55mV/G at 1.8V and 3V. The typical null voltage offset is less than 1% of VDD. The device has a typical input referred rms noise of 0.36G and 0.24G at 1.8V and 3.0V. Designed for battery powered consumer equipment to office equipment, home appliances and industrial applications, the AH8500 can operate over the supply range of 1.6V to 3.6V and uses an externally controlled ENABLE pin clocking system to control operating modes and sampling rates and to minimize the power consumption. The typical average operating supply current is between 8.9µA during “Sleep” mode and 1.16mA at maximum sampling rate 1.8V. With a conversion pulse every 50ms at the ENABLE pin, the device achieves a micropower operation with the power consumption of 22µW typical at 1.8V supply. To minimize PCB space the AH8500 is available in small low profile U-DFN2020-6. Features Linear Hall Effect Sensor with +/-430G Sense Range and Output Voltage with 8-bit resolution Supply Voltage of 1.6V to 3.6V Sensitivity: 2.1mV/G and 3.55mV/G at 1.8V and 3V at +25 oC Low Offset Voltage Low Average Supply Current 8.9µA Typical in Sleep Mode (Default) at 1.8V 1.01mA Typical in Auto-Run Mode ( 6.25kHz) at 1.8V 12µA Typical in External Drive Mode with 20Hz Sample Rate at 1.8V 1.16mA Typical in External Drive Mode with 7.14kHz Sample Rate at 1.8V Chopper Stabilized Design with Superior Temperature Stability, Minimal Sensitivity Drift, Enhanced Immunity to Physical Stress Output Voltage Maintained at „Sleep‟ Mode -40°C to +85°C Operating Temperature High ESD Capability of 6kV Human Body Model Small Low Profile U-DFN2020-6 Package Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3) Pin Assignments (Top View) VDD GND NC NC OUTPUT ENABLE 1 2 3 6 5 4 Exposed Pad U-DFN2020-6 Applications High Accuracy Level, Proximity, Position and Travel Detection Button Press Detection in Digital Still, Video Cameras and Handheld Gaming Consoles Accurate Door, Lids and Tray Position Detection Liquid Level Detection Joy Stick Control – Gaming and Industrial Applications Contact-Less Level, Proximity and Position Measurement in Home Appliances and Industrial Applications Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. 2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated‟s definitions of Halogen- and Antimony-free, "Green" and Lead-free. 3. Halogen- and Antimony- free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds. |
