good quality hall element linear hall switch linear hall element HX248

  HX248 Hall-effect Sensor is a Temperature stable, stress-resistant , micro-power Switch. Superior high-temperature performance is made possible through a dynamic offset cancellation that utilizes chopper-stabilization. This method reduces the offset voltage normally caused by device over molding, temperature dependencies, and thermal stress.   HX248 includes the following on a single silicon chip: voltage regulator, Hall voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, open-drain output. Advanced CMOS wafer fabrication processing is used to take advantage of low-voltage requirements, component matching, very low input-offset errors, and small component geometries.   This device requires the presence of omni-polar magnetic fields for operation.   HX248 is rated for operation between the ambient temperatures –40℃ and + 85℃ for the E temperature range. The four 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),Tsot-23 is an ST(0.7 mm nominal height) ,a miniature low-profile surface-mount package, while package UA is a three-lead ultra-mini SIP for through-hole mounting.   The package type is in a lead Halogen Free version was verified by third party Lab.   Features and Benefits u CMOS Hall IC Technology u Solid-State Reliability u Micro power consumption for battery-powered applications u Omni polar, output switches with absolute value of North or South pole from magnet u Operation down to 2.5 V and Max at 3.5V. u High Sensitivity for direct reed switch replacement applications u Multi Small Size option u Custom sensitivity selection is available in optional package. u Pb Free/Green chip is qualified by third party lab.     Applications l Solid state switch l Handheld Wireless Handset Awake Switch ( Flip Cell/PHS Phone/Note Book/Flip Video Set) l Lid close sensor for battery powered devices l Magnet proximity sensor for reed switch replacement in low duty cycle applications             Payment Terms: 1)  We accept T/T, PayPal, WesternUnion, MoneyGram, Escrow, Alipay or Cash. 2) Pls send us payment receipt for us to follow payment status to prepare deliveryintime.   Shipping terms: 1)  For general goods, we will pack and send your goods within 4-7 working days after your payment is received.  2)  We will inform you the exact develop and delivery time if there is no stock and takes time to develop. 3)  We usually ship by DHL, UPS, TNT, FedEx, Aramex or EMS.
