The AH3663 is a digital omnipolar-latch Hall IC with single output. It has good temperature stability and operates over a temperature range of -40°C to 85°C with latch function.
The AH3663 Hall-effect sensor includes the following on a single silicon chip: reverse voltage protector, voltage regulator, temperature compensation circuit, Hall-voltage generator, signal amplifier, Schmitt trigger and open-drain output driver, etc.
The AH3663, produced with CMOS technology, is asked for lower supply voltage and less power supply. It is available in two package types: SOT-23-3L (Type M) and TO-92UA (Type UA). Each package is lead (Pb) free, with 100% matte tin plated leadframes.
