App note: microcontrollers and triacs easily connected


Here’s an application note from NXP on how to easily connect main triacs and microcontrollers.

This application note describes the easy connection of NXP LPC microcontrollers and three – quadrant (Hi-Com) triacs to control any resistive or inductive load at mains voltage. A one-for-all control method is presented that uses an innovative, patented, current zero-crossing detection method without need for a shunt resistor in the load current line.
