| Description & Applications | Chopper-Stabilized Hall Effect Latch The A3282 Hall-effect sensor is a temperature stable, stress-resistant latch. Superior high-temperature performance is made possible through an Allegro® patented dynamic offset cancellation that utilizes chopper-stabilization. This method reduces the offset voltage normally caused by device overmolding, temperature dependencies, and thermal stress. The A3282 complements the current Allegro family of chopper-stabilized latching sensors. The A3282 includes the following on a single silicon chip: voltage regulator, Hallvoltage generator, small-signal amplifi er, chopper stabilization, Schmitt trigger, and a short circuit protected open-drain output. Advanced BiCMOS 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 fi elds for operation. In the presence of a south polarity fi eld of suffi cient strength, the device output latches on, and only switches off when a north polarity fi eld of suf-fi cient strength is present. The A3282 is rated for operation between the ambient temperatures –40°C and 85°C for the E temperature range, and –40°C to 150°C for the L temperature range. The two package styles available provide magnetically optimized solutions for most applications. Package LH is an SOT23W, a miniature low-profi le surface-mount package, while package UA is a three-lead ultramini SIP for throughhole mounting. Each package is available in a lead (Pb) free version, with 100% matte tin plated leadframes.
