NOTE: Pin numbers refer to the 20 lead SOIC package. Please check PINOUT diagrams for QFN pin numbers. VCC (Positive Supply Voltage) Pin 1 - This power pin supplies power to the IC; nominally 12V. It should be bypassed directly to the GND pin with a 0.1µF low ESR/ESL capacitor. GND (Signal Ground) Pin 6 - This power pin is the reference ground connection f.
