iA1188D Hall-effect sensor is a temperature stable, stress-resistant sensor. Superior hightemperature performance is made possible through a dynamic offset cancellation that utilizes chopperstabilization. This method reduces the offset voltage normally caused by device over molding, temperature dependencies, and thermal stress.
iA1188D 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.
iA1188D is rated for operation between the ambient temperatures -40℃ to 125℃. The two package styles available provide magnetically optimized solutions for most applications. iA1188D is an SOT-23, a miniature low-profile surfacemount package.
Package is Halogen Free standard and which have been verified by third party lab.
