说明
AW35602 is a single chip USB Type-C port protection solution, it integrates four channels of switches with OVP protection. CON_LSP1/2 pins can tolerate up to 24V DC, and CON_HSP1/2 pins can tolerate up to 28V DC. LSP switch can be used to protect CC of Type-C, and HSP switch can be used to protect D+/D- in SBU of Type-C.
AW35602 will disconnect all four channels of switches when any pin of CON_LSP1/2 in CON_HSP1/2 is above the OVP threshold, LSP1, LSP2, HSP1 and HSP2 in system side are protected from the high voltage. When OVP is detected, FLAGB pin is pulled down.
AW35602 integrates dead battery circuits in CON_LSP1 and CON_LSP2.
AW35602 integrates ±80V IEC61000-4-5 surge protection on CON_LSP1 and CON_LSP2, and also provides ±8kV contact discharge and ±12kV air discharge IEC61000-4-2 ESD protection on CON_LSP1 and CON_LSP2.
