MAX6920 - Serial-Interfaced VFD Tube Driver

Description

The MAX6920 is a 12-output, 76V, vacuum fluorescent display (VFD) tube driver that interfaces a multiplexed VFD tube to a VFD controller such as the MAX6850

MAX6853 or to a microcontroller.

The MAX6920 is also ideal for driving either static VFD tubes or telecom relays.

Features

  • 5MHz Industry-Standard 4-Wire Serial Interface.
  • 3V to 5.5V Logic Supply Range.
  • 8V to 76V Grid/Anode Supply Range.
  • Push-Pull CMOS High-Voltage Outputs.
  • Outputs can Source 40mA, Sink 4mA Continuously.
  • Outputs can Source 75mA Repetitive Pulses.
  • Outputs can be Paralleled for Higher Current Drive.
  • Any Output can be Used as a Grid or an Anode Driver.
  • Blank Input Simplifies PWM Intensity Control.
  • Small.

MAX6920 12-Output, 76V, Serial-Interfaced VFD Tube Driver General Description The MAX6920 is a 12-output, 76V, vacuum fluorescent display (VFD) tube driver that interfaces a multiplexed VFD tube to a VFD controller such as the MAX6850–MAX6853 or to a microcontroller. The MAX6920 is also ideal for driving either static VFD tubes or telecom relays. Data is inputted using an industry-standard 4-wire serial interface (CLOCK, DATA, LOAD, BLANK) for compatibility with both industry-standard drivers and Maxim’s VFD controllers. For easy display control, the active-high BLANK input forces all driver outputs low, turning the display off, and automatically puts the MAX6920 into shutdown mode. Display intensity may also be controlled by pulse-width modulating the BLANK input.
