Description
The ML9222 is a CMOS controller and driver used for Duplex or Triplex vacuum fluorescent display tubes. It is composed of 32-segment driver outputs and 3-grid pre-driver outputs, allowing it to directly control up to 96-segment VFD tubes. ML9222 comes with a digital dimming function, 8-ch ADC, 5 x 5 keyscan circuit, and an encoder type switch interface. It only requires four signal lines to interface with a microcontroller: DATA I/O, CLOCK, CS, and INT.
Specifications and features
- Supply voltage (VDD): 8 to 18.5V (Built-in 5V regulator for logic)
- Duplex/Triplex selectable
- Applicable VFD tube: 2 Grids x 32 Anodes VFD tube, 3 Grids x 32 Anodes VFD tube
- 32-segment driver outputs: IOH=-5mA at VOH=VDD-0.8V (SEG1 to 22), IOH=-10mA at VOH=VDD-0.8V (SEG23 to 32)
- 3-grid pre-driver outputs: IOL=10mA at VOL=2V
- Built-in digital dimming circuit (10-bit resolution)
- Built-in 8-ch A/D converter
- Built-in 5 x 5 keyscan circuit
- 3 interface circuits for an encoder type rotary switch
- Built-in oscillation circuit (external R and C)
- Built-in Power-On-Reset circuit
- Package: 80-pin plastic QFP (QFP80-P-1420-0.80-BK) Product name: ML9222GA
Application Scenarios
The ML9222 is well-suited for use as a controller for Duplex or Triplex vacuum fluorescent display tubes. It is ideal for electronics applications that require digital dimming function, ADC, and keyscan circuit.
