The application shown in Figure 8-1 demonstrates how to generate a ±12V PWM signal that is created by toggling the TMUX6219-Q1. This PWM signal generated by the EVSE on the control pilot line signals to the car the available current of the charger, and the car will respond with a charging status. This handshake results in a safe method for supplying power to vehicle. The TMUX6219-Q1 can support 1.8V logic signals on the control input, allowing the device to interface with low logic controls of an FPGA or MCU. The TMUX6219-Q1 can be operated without any external components except for the supply decoupling capacitors. The select pin has an internal pull-down resistor to prevent floating input logic. All inputs to the switch must fall within the recommend operating conditions of the TMUX6219-Q1 including signal range and continuous current. For this design with a positive supply of 12V on V_DD, and negative supply of ?12V on V_SS, the signal range can be 12V to ?12V. The max continuous current (I_DC) can be up to 330mA as shown in the Recommended Operating Conditions table for wide-range current measurement.
