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.
