VG481V1 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. The sensor IC is protected from abnormal operation at low voltage by a power-on rest circuit. The output circuitry con

VG481V1 General 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 sl.
