VG481V1
Back Biased Hall-effect Speed Sensor Integrated Circuit (IC)
DESCRIPTION
The VG481V1 contains a dual peak detecting circuit that is coupled with a Hall-effect element to detect the speed of a ferrous gear tooth target wheel.
A biasing magnet provides a changing magnetic field as the target wheel moves past the senor IC.
The sensor IC functions in reference to peak and slot magnetic levels.
The sensor IC output is in either a high state or a low state, which corresponds to the target tooth/slot features.
The VG481V1 IC consists of a
voltage regulator, clock/oscillator, Hallelement, amplifier, internal peak/valley track and hold circuits, comparator, and open collector output stage.
