AH8102

AiT Semiconductor Inc. www.ait-ic.com AH8102 HALL SWITCH MICROPOWER, ULTRA-SENSITIVE HALL EFFECT SWITCH DESCRIPTION FEATURES AH8102 is with two Hall effect plates and a CMOS  output driver, mainly designed for battery–powered,  hand-held equipment (such as Cellular and Cordless  Phone, PDA). E.g. as an On/Off switch in Cellular Flip-Phones, with battery operating voltages of 2.4V-5.5V. Either north or south pole of sufficient strength will turn the output on. The output will be turned off under no magnetic field. While the magnetic flux density (B) is larger than operate point (Bop), the output will be turned on (low), the output is held until B is lower than release point (Brp) ,then turned         off. Micropower operation Operation with North or South Pole 2.4V to 5.5V battery operation Chopper stabilized Superior temperature stability Extremely Low Switch-Point Drift Insensitive to Physical Stress Good RF noise immunity ESD ＞ 4KV in human body mode Lead Free Finish Available in SOT-553 Package The AH8102 is available in SOT-553 package.
