UH8013

UNISONIC TECHNOLOGIES CO., LTD UH8103 Preliminary HALL EFFECT MICRO SWITCH IC BiCMOS IC  DESCRIPTION The UH8103 is a low power, pole independent Hall-effect switch with a latched digital output driver. It can work in 2.5 volt supply. Either a north or south pole of sufficient flux will turn the output on; in the absence of a magnetic field, the output is off. When a magnetic field enters the hall element and exceeds the operate point BOPS(or less than BOPN) the output turns on (output is low). When the magnetic field is below the release point BRPS , the output turns off (output is high). It is designed with open drain configuration and connecting a pull up resistor from Output to VDD is necessary.  FEATURES *Micropower Operation *2.5V to 5.5V Battery Operation *Offset Canceling Technology *Independent of North or South Pole Magnet *Superior Temperature Stability *Extremely Low Switch-Point Drift  APPLICATIONS *Micro Switch *Handheld Wireless Application Wake Up Switch *Clamp Shell Type Application Switch *Magnet Switch in Low Duty Cycle Applications  ORDERING INFORMATION Ordering Number UH8013G-AE3-R Note: Pin Assignment: O: Output I: VDD G: GND Package SOT-23 Pin Assignment 123 OIG 3 1 2 SOT-23 (EIAJ SC-59) Packing Tape Reel  MARKING www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 4 QW-R502-513.b UH8103  BLOCK DIAGRAM Preliminary BiCMOS IC  TYPICAL CIRCUIT GND 3 2 VDD 1 Digital Output OUTPUT Pull up resistor (recommend 50KΩ)...
