Xinyan electronic inductive proximity switch chip series has been designed in different package types such as GC5355/GC5505. The series has been added to the GC5515 and is available in DFN-14L package.

1. The product description:

GC5515 is an application-specific integrated circuit with short-circuit protection for inductive proximity switch applications. It can be widely used in various proximity sensors or proximity control systems. It can also be used to make a variety of inductive detection instruments, such as inductive tachometers. Wait. The GC5515 consists of an oscillator, a switching circuit, and an amplifying output circuit. The basic working principle is to form an LC high-frequency resonant circuit by using an external inductor and capacitor, and generate an alternating magnetic field in the resonant loop. When the detected metal target approaches the magnetic field and reaches the sensing distance, an eddy current is generated in the detected metal target and the energy of the oscillator is taken up, so that the amplitude of the oscillator is attenuated or stopped. The oscillation and oscillation of the oscillator are processed by the post-amplifier circuit and converted into a switching signal to trigger the drive control device, thereby achieving the purpose of non-contact detection. GC5515 has the characteristics of high integration, wide working voltage, large output current, adjustable control distance, few peripheral circuits, convenient application and stable and reliable operation. Compared with the inductive proximity switching scheme consisting of general discrete components, the GC5515 integrated chip solution has better consistency and stability, so it is especially suitable for high reliability and high reliability.
