Mobile Charger Common-Mode Noise Measurement

Mobile Charger Common-Mode Noise Measurement

Common-mode noise voltage pulses from AC-DC chargers can affect the signal reception of capacitive panels during charging, which may lead to inaccurate touch readings or false touch signals. This has prompted cell phone manufacturers and the International Electrotechnical Commission (IEC) to jointly develop the IEC 62684 Standard to harmonize charger interfaces. Charger manufacturers are looking […]
