CJH0104

JIANGSU CHANGJING ELECTRONICS TECHNOLOGY CO., LTD MicroPower, Ultra-Sensitive Omnipolar Hall Effective Switchs CJH0104 General Description CJH0104 is a micropower, ultra sensitive hall effect switch. It is mainly designed for battery-powered, hand held equipment. CJH0104 includes hall sensor, a small-signal amplifier, dynamic offset cancellation and CMOS output. Superior high-temperature performance is made possible through Dynamic Offset Cancellation, which reduces the residual offset voltage normally caused by device package over molding, temperature dependencies, and thermal stresses.Either North or South pole of sufficient strength will turn the output on. CJH0104 is available in TO-92S packages.The operating temperature is -40℃ to 150℃. Features Application  Wide operating voltage, 2~5V  PDA, IPAD  Micro power  Cellular phone  Operating with North or South pole  Superior temperature stability  Extremely Low Switch-point Drift  ESD（HBM）6000V  Small package size Function Block Diagram www.jscj-elec.com 1 Rev. - 1.0 Electrical Characteristics Ordering Information Part No. CJH0104 Packing Form Package Code bulk，1000 pcs/bulk TO-92S Output Voltage VS.
