UNISONIC TECHNOLOGIES CO., LTD UH8106 Advance CMOS IC CMOS, OMNI-POLAR, LOW POWER HALL SENSOR DESCRIPTION UH8106 is a low-power integrated Hall switch designed to sense the applied magnetic flux density and give a digital output, which indicates the present condition of the magnitude sensed. It mainly designed for battery-powered system and hand-held equipment, such as cellular flip-phones and PDA’s, in which power consumption is one major concern. There are three output types (Internal 100K pull-up resistor, NMOS open-drain and CMOS push-pull ) and two ranks of magnetic characters for user to choose. FEATURES *Omni-polar magnetic type *2.2V 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 Note: UH8106XXG-AE3-R UH8106XXG-G03-B UH8106XXG-G03-K Pin Assignment: I: VCC O: VOUT Package SOT-23 SIP-3 SIP-3 Pin Assignment 1 2 3 O I G I G O I G O Packing Tape Reel Tape Box Bulk G: GND www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 6 QW-R118-024.a UH8106 Advance CMOS IC MARKING SOT-23 SIP-3 PIN CONFIGURATIONS PIN DESCRIPTION PIN NAME TYPE DESCRIPTION VOUT O Output VDD P/I Power Supply Input GND P Ground Note: P: power supply, I: input, O: output PRODUCT LIST Internal pull-up resistor output PRODUCT NAME UH8106I1 UH8106I2 OUTPUT Internal pull-up resistor Internal pull-up resistor VOUT (When |B|>|BOP|) LOW LOW |BOP| 1.3~2.3 mT 1.0~4.0 mT NMOS open-drain output PRODUCT NAME UH8106N1 UH8106N2 OUTPUT NMOS open-drain NMOS open-drain VOUT (When |B|>|BOP|) LOW LOW |BOP| 1.3~2.3 mT 1.0~4.0 mT CMOS push-pull output PRODUCT NAME UH8106C1 UH8106C2 OUTPUT CMOS push-pull CMOS push-pull VOUT (When |B|>|BOP|) LOW LOW |BOP| 1.3~2.3 mT 1.0~4.0 mT UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 6 QW-R118-024.a UH8106 Advance CMOS IC BLOCK DIAGRAM Internal pull-up resistor output NMOS open-drain output CMOS push-pull output UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 3 of 6 QW-R118-024.a UH8106 Advance CMOS IC ABSOLUTE MAXIMUM RATING (TA=25°C, unless otherwise specified) PARAMETER Magnetic Flux Density Supply Voltage Output Current SYMBOL B VDD IO RATINGS Unlimited 7 1 SIP-3 400 Power Dissipation PD SOT-23 200 Maximum Junction Temp TJ 150 Operation Temperature TOPR -40 ~ +85 Storage Temperature TSTG -65 ~ +150 Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
