General DescriptionThe AH3662 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 AH3662 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 AH3662, 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.
Low Average PowerInternal timing circuit activates the IC for 45 μs and deactivates it for the remainder of the period (45 ms). A short "awake" time allows for stabilization prior to the sampling and data latching on the falling edge of the timing pulse. The output during the "sleep" time is latched in the last sampled state. The supply current is not affected by the output state.
