Description
The A3245 integrated circuit is an omnipolar, ultrasensitive Hall-effect switch with a digital output. This sensor has an integrated regulator permitting operation to 24 V, making it the first omnipolar switch available for operation to 24 V. This device is especially suited for operation over extended temperature ranges, up to +150°C. Superior high-temperature performance is made possible through an Allegro® patented dynamic offset cancellation, which reduces the residual offset voltage normally caused by device overmolding, temperature excursions, and thermal stress.
The A3245 Hall-effect switch includes the following on a single silicon chip: voltage regulator, Hall-voltage generator, small signal amplifier, 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.
