HX6571 Specifications Ultra High Sensitivity Hall Effect Latch HX6571 Hall-effect sensor is a temperature stable, stress-resistant sensor. 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. HX6571 includes the following on a single silicon chip: voltage regulator, Hall voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, Advanced DMOS 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 both south and north polarity magnetic fields for operation. In the presence of a south polarity field of sufficient strength, the device output sensor on, and only switches off when a north polarity field of sufficient strength is present. HX6571 is rated for operation between the ambient temperatures 40 and 85 for the E temperature range, and 40 to 125 for the K temperature range. The two package styles available provide magnetically optimized solutions for most applications. Package SO is an SOT-23, a miniature low-profile surface-mount package, while package UA is a three-lead ultra mini SIP for through-hole mounting. Packages is Halogen Free standard and which have been verified by third party lab. Features and Benefits DMOS Hall IC Technology. Reverse bias protection on power supply pin.
