Analog Switches - Special Purpose Replacement Considerations

The datasheet explicitly states the part is obsolete and directs users to use the PI3EQX10612 as the replacement.

Analog Switches - Special Purpose FAQ

How is the source current mode configured?

The source current mode is set using the SRC_CUR pin or via I2C register bits. Valid configurations include Default (GND), 1.5A (No Connection), and 3A (VDD).

What are the available I2C slave addresses?

The USB-C Detector uses addresses CAh, 8Ah, EAh, or AAh depending on the ADDR1 resistor value. The ReDriver uses A4h, A0h, A6h, or A2h respectively.

Can the device operate without I2C control?

Yes, the ReDriver can operate in Pin Control Mode where channel assignment and status are determined by the logic levels on the ADDR1, PORT1, and PORT0 pins.
