This document presents the application of the VNI4140K quad-channel high-side driver and provides recommendations on how to optimize its ESD immunity level.
The document focuses on the VNI4140K, a quad-channel high-side driver designed for industrial applications. It addresses how to achieve required ESD immunity levels in accordance with IEC 61000-4-2 standards when using this specific device.
To optimize performance, the note details three application solutions involving external components: capacitive filters (C filters), IT LC filters, and dual LC filters. These configurations are intended to protect the device against radio-frequency disturbances and transient events.
The immunity level is 2000 V.
The supply voltage is 24 VDC and inputs/outputs are OFF.
A wire-wound, air-core type inductor is recommended.
