• 5V compliant, and still talks to a 3.3V microcontroller
• 6 “address select” pins for configuring up to 62 ICs on a single I2C bus
• PWM frequency adjustable up to approximately 1.6kHz
• 12-bit frequency resolution (equates to about 4µs resolution at 60Hz refresh rate)
• Configurable as push-pull or open-drain output
• Output enable pin available for outside-the-microcontroller “shut it down!” control.
