High sensitivity Unipolar Hall switch sensor 1.Product Introduction 2.Function AH508 is a highly sensitive unipolar Hall - AEC-Q100 Grade 0 Automotive Level switch chip designed based on BCDMOS technology. The chip includes temperature pensation, parator, and output driver. In addition, mechanical stress has little effect on the magnetic parameters of the chip. The series of chip sensors is suitable for Certification - Operating Vcc Range:2.7V~30V - ESD：±12k V - High mechanical stress suppression ability - Temperature range：-40℃～150℃ - The decrease of magnetic flux density caused by industrial and automotive applications, with an rising temperature is pensated by the built- ambient temperature range of -40 ℃ to 150 ℃ and in negative temperature coefficient supply voltage range of 2.7V to 30V. AH508 - Reverse-voltage protection at Vcc pin provides a variety of packages to customers:TO92S、 - Suitable for automobiles and industries SOT23（small）、SOT23. All packages are Ro Hs - Overvoltage protection up to 40V pliant. The product has passed AEC-Q100 certification. 3.Application - Speed and RPM sensing - Tachometer sensor、Flow-rate sensing - DC motor, motor and fan control, robotics control - Proximity sensor、Position sensor - Seat belt buckles、hood/trunk/door latches - Sunroof/convertible top/tailgate - Liftgate activation - Brake/clutch pedals - Electric power steering(EPS) - Transmission shifting - Wiper motor REV1.2 06/2023 .alfaelecs. 西安中科阿尔法电子科技有限公司 High sensitivity Unipolar Hall switch sensor 4.Products packaging Part No. AH508UA AH508SU AH508SS Packages TO92S SOT23-3L SOT23（small） temperature range -40℃～150℃ -40℃～150℃ -40℃～150℃ Packing 1000pcs/bag 3000pcs/reel 3000pcs/reel REV1.2 06/2023 .alfaelecs. 西安中科阿尔法电子科技有限公司...
