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.
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 contains short circuit protection. The voltage regulator contains reverse connection protection. The slicing level is derived from the stored peak and valley values. A start-up algorithm holds the output.
