Maxim Integrated MAX6920AWP+ VFD Tube Drivers

The Maxim Integrated MAX6920AWP+ is a state-of-the-art Vacuum Fluorescent Display (VFD) tube driver that is designed to cater to the needs of high-voltage display applications. This 20-output, 76V, serial-interfaced VFD tube driver is a perfect solution for driving large VFD panels, offering a seamless interface for a variety of display applications.

With its compact 20-pin SO package, the MAX6920AWP+ is engineered to save space on your PCB while delivering high performance. This driver operates with a 2.7V to 5.5V logic supply voltage, making it compatible with a range of microcontrollers and logic devices. Its high voltage operation, up to 76V, allows for the driving of large VFD tubes that require higher voltages for the phosphor to illuminate.

The MAX6920AWP+ features a serial interface which simplifies the connection to microcontrollers, as it requires fewer I/O lines. This serial interface is SPI™/QSPI™/MICROWIRE™ compatible, offering versatility and ease of integration into existing systems. The device has a 25MHz serial clock frequency, enabling fast data transfer rates and responsive display updates.

One of the key advantages of the MAX6920AWP+ is its built-in slew-rate limited segment and grid outputs. This feature minimizes electromagnetic interference (EMI), making it an ideal choice for noise-sensitive applications. The outputs are also open-drain, which means multiple drivers can be paralleled for increased segment current or for driving higher voltage displays.

The MAX6920AWP+ also boasts an over-temperature shutdown feature that protects the device from damage due to excessive heat. This ensures long-term reliability and stable operation in a variety of environmental conditions.

Whether you're designing for industrial control panels, consumer electronics, or any application that requires reliable and high-quality VFD tube driving, the Maxim Integrated MAX6920AWP+ offers a robust, efficient, and easy-to-use solution that will elevate the performance and aesthetic of your displays.
