Automotive SPD-SmartGlass driver reference design

This reference design from Texas Instruments details how to drive various forms of electronically dimmable glass, including SPD-SmartGlass and APD Glass from a car battery. This illustrates how to make a DC/AC inverter using the LM5155-Q1 boost converter with a charge pump, two UCC27712-Q1 half bridge drivers, and a TMS320F2807 microcontroller for PWM creation and system monitoring.

The features of this include:

  • 120 Vrms AC output.
  • 100mA driving capability.
  • Controllable output amplitude for intermediate levels of glass dimming.
  • This circuit design is tested and includes gerbers, schematics, and BOM.
