These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to Absolute Maximum Ratings for extended periods can affect device reliabili ty. All voltages unless otherwise stated and measured with respect to GND. 5. Test condition: device mounted on 1” 1” FR-4 substrate PCB, 2oz copper, with minimum recommended pad layout. 6. It’s essential to connect VCC pin with a SMD ceramic capacitor (0.1 μF to 0.47μF) to filter out the undesired switching noise for stable operation. This capacitor should be placed as close to IC as possible. 7. Test condition is RISET = 100k. (This mean is IDIM = 100μA).
