Page 3: Safety Information
General safety instructions ESD protection ESD can damage boards and associated components. Infineon recommends that the user perform procedures only at an ESD workstation. If an ESD workstation is unavailable, use appropriate ESD protection by wearing an antistatic wrist strap attached to the chassis ground (any unpainted metal surface) on the board when handling parts. - Page 4 WLC1150 MP-A2 50-W wireless power transmitter (REF_WLC_TX50W_N1) user guide Safety information Monitor the coil interface’s surface temperature during prolonged usage. Ensure that there are no foreign metallic objects on the REF_WLC_TX50W_N1 board’s charging interface surface soon after the phone/receiver is placed to avoid miscalibration and overheating.
