UH8100

UNISONIC TECHNOLOGIES CO., LTD UH8100 LOW POWER HALL EFFECT SWITCH CMOS IC  DESCRIPTION UH8100 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. The typical power consumption of UH8100 is down to 15uW at 2.75V supply. For UH8100, the output will be high when no magnetic field is applied and be low when the applied magnetic flux density is stronger than the switching threshold. The difference between UH8100A and UH8100B is that UH8100A consumes less power than UH8100B in the Hall sensor operation.  FEATURES * Micro power Operation * 2.5V to 5.5V Battery Operation * Offset Canceling Technology * Superior Temperature Stability * Extremely Low Switch-Point Drift * Insensitive to Physical Stress  ORDERING INFORMATION Ordering Number UH8100AG-AE3-R UH8100BG-AE3-R Note: Pin Assignment: O: VOUT, I: VDD, G: GND Package SOT-23 SOT-23 3 1 2 SOT-23 (EIAJ SC-59) Pin Assignment 123 OIG OIG Packing Tape Reel Tape Reel  MARKING UH8100A www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd UH8100B 1 of 4 QW-R502-413.E UH8100  PIN CONFIGURATIONS  PIN DESCRIPTION PIN NAME PIN TYPE PIN DESCRIPTION VOUT O Digital Output VDD P Power Supply GND G Ground Note: O=Output, P=...
