onsemi FSA1153 USB Type-C™ Audio/UART Analog Switch
onsemi FSA1153 USB Type-C™ Audio/UART Analog Switch is a bi-directional, high-speed USB 2.0 Type-C Audio and UART Analog Switch with Overvoltage Protection (OVP). Configured as a Double Pole, Triple Throw (DP3T) switch, the FSA1153 switch is designed to protect the Type-C USB 2.0 port from being damaged by high voltage. The FSA1153 provides receptacle side OVP function on the USB 2.0 data pins and will turn off the relative switch once the voltage level on DN_L or DP_R Pin is over the OV threshold, withstanding up to 20.5V.
The FSA1153 USB Type-C Audio/UART Analog Switch is offered in a compact 12-bump Wafer Level Chip Scale Package (WLCSP), ideal for space-constrained applications. This device is Pb-Free and RoHS-compliant.
