HX6659 (T) Specifications CMOS Ratio-Metric Linear Hall Effect IC HX6659-B,HX6659-C,HX6659-D, a linear Hall-effect sensor, is composed of Hall sensor, linear amplifier and Totem-Pole output stage. It features low noise output, which makes it unnecessary to use external filtering. It also can provide increased temperature stability and accuracy. The linear Hall sensor has a wide operating temperature range of -40 to +105, appropriate for commercial, consumer, and industrial environments. The high sensitivity of Hall-effect sensor accurately tracks extremely weak changes in magnetic flux density. The linear sourcing output voltage is set by the supply voltage and in proportion of vary of the magnetic flux density. Typical operation current is 2.5 mA and operating voltage range is 2.8 volts to 6.0 volts. Trim version is available for an ultra low offset products. The three package styles available provide magnetically optimized solutions for most applications. Package types SO is an SOT-23(1.1 mm nominal height),SQ is an QFN2020- 3(0.5 mm nominal height),a miniature low-profile surface-mount package, while package UA is a three-lead ultra-mini SIP for through-hole mounting. Features and Benefits Operating Voltage Range: 2.8V~6.0V Power consumption of 2.5 mA at 5 V for energy efficiency DC Low-Noise Operation Linear output for circuit design flexibility Totem-Pole for a stable and accurate output Responds to either positive or negative gauss Magnetically Optimized Package for UA,SQ,SO Trim version is precise on offset Robust ESD performance Applications Current sensing Motor control Position sensing Magnetic code reading Rotary encoder Ferrous metal detector Vibration sensing Liquid level sensing Weight sensing HX6659 (T) Specifications CMOS Ratio-Metric Linear Hall Effect IC Part No. Temperature Suffix Package Type HX6659IUA-B I (-40 to +105) UA (TO92-3L) I (-40 to +105) UA (TO92-3L) HX6659IUA-C HX6659IUA-D I (-40 to +105) UA (TO92-3L) HX6659ISQ-B I (-40 to +105) SQ (QFN2020-3) I (-40 to +105) SQ (QFN2020-3) HX6659ISQ-C HX6659ISQ-D I (-40 to +105) SQ (QFN2020-3) HX6659ISO-B I (-40 to +105) SO(SOT-23) I (-40 to +105) SO(SOT-23) HX6659ISO-C HX6659ISO-D I (-40 to +105) SO(SOT-23) HX6659IUA-B-T I (-40 to +105) UA (TO92-3L) HX6659IUA-C-T I (-40 to +105) UA (TO92-3L) HX6659IUA-D-T I (-40 to +105) UA (TO92-3L) HX6659ISQ-B-T I (-40 to +105) SQ (QFN2020-3) HX6659ISQ-C-T I (-40 to +105) SQ (QFN2020-3) HX6659ISQ-D-T I (-40 to +105) SQ (QFN2020-3) HX6659ISO-B-T I (-40 to +105) SO(SOT-23) HX6659ISO-C-T I (-40 to +105) SO(SOT-23) HX6659ISO-D-T I (-40 to +105) SO(SOT-23) Functional Diagram
