VN808-E Application Field and Working Principle

The VN808-E from IXYS is a high-current, low-voltage MOSFET driver and buffer. This compact and versatile 8-channel switch is capable of driving large MOSFETs up to 200A and is ideal for low impedance and low EMI requirements. The VN808-E is commonly used in power distribution switches, load drivers, and other applications in which high current is needed.

The VN808-E is well suited for use in high-power, high-current applications including motor controllers, LED lighting, and HVAC systems. The unit is designed to handle large inrush currents and has very low resistance. The VN808-E has a very low propagation delay time, allowing it to be used in applications with high switching times. It can be used in both standard and customized systems.

VN808-E Operating Principle

The VN808-E’s operating mechanism is based on a power MOSFET with combination of an optimized drive-channel bridge and an integrated buffer-amplifier. This combination enables the device to drive high currents. The switching speed of the VN808-E is based on the integrated short-delay mode. This short-delay mode has a small impact on the switching time, allowing it to operate at high speed.

The VN808-E is capable of driving up to 200A and has a package size of only 4.3mm x 6.5mm. In addition, its advanced over-voltage and over-temperature protection make it ideal for applications which require high power but have very limited space. The device also features integrated circuits which allow it to be used in a variety of different systems. Its high performance and low cost make it suitable for a wide range of applications.

The VN808-E is fully compliant with both international and US standards including UL and IEC. Its high current capabilities, low on-resistance, and ease of use make it a great choice for power distribution applications, including motor controllers, LED lighting, and HVAC systems.
