Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. 2. To use at temperature above TA=25°C reduce 4.68mW/°C (On 70.00mm×1.6mm glass epoxy board). 3. This value is mot to be over Pd, VCC=4.0V~6.0V At VCC=2.2V~4.0V, output current tolerance reduces.  OPERATING CONDITIONS UNIT V V PARAMETER SYMBOL RATINGS Operating Supply Voltage Range VCC 2.2~6.0 Hall Input Voltage Range VH 0.4~VCC-1.1 Notes: 1. This product is not designed for production against radioactive rays. 2. This document may be strategic data subject to COCOM regulations.  ELECTRICAL CHARACTERISTICS (Unless otherwise specified TA=25°C, VCC=5V) SYMBOL ICC VHOFS VO GIO VFGL VHYS TON TOFF VHB TEST CONDITIONS MIN TYP 5 0.32 48 ±10 0.50 5.0 1.3 MAX 8 ±6 0.49 51 0.3 ±15 0.65 6.5 1.5 UNIT mA mV V dB V mV sec sec V PARAMETER Supply Current Input Offset Voltage Output Voltage Input-Output Gain FG Low Voltage Input Hysteresis Voltage Lock detection ON Time Lock Detection OFF Time Hall Bias Voltage IO=250mA upper and lower total 45 IFG=3mA ±5 0.35 3.5 1.1 IHB=-5mA UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 3 of 4 QW-R502-981.a http://www.Datasheet4U.com FC8779  Preliminary CMOS IC TYPICAL APPLICATION CIRCUIT UTC assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all UTC products described or contained herein.
