DP3T USB Type C Audio and UART Analog Switch with OVP



FSA1153 is a bi−directional, low power consumption, high speed USB 2.0 Type−C, Audio and UART analog switch with overvoltage protection function. Configured as a ouble−Pole, Triple Throw (DP3T) switch. FSA1153 protection function is to protect the Type−C USB 2.0 port pins from getting damage by high voltage; it provides receptacle side OVP function on USB 2.0 data pins, it will turn off the relative switch once the voltage level on DN_L or DP_R is over the OV threshold, it can withstand up to 20.5 V. The device will be damaged once the voltage on DN_L or DP_R is over 20.5 V.
