1. Key Features
The Automotive MP-A9_Rev1.0
(MP-A9_Rev1_SCH-29323_B2,
MP-A9_Rev1_LAY-29323_B2) wireless
charging TX demo is used to transfer power
wirelessly to a charged device. A charged device
can be any electronic device equipped with a
dedicated Qi wireless charging receiver.
The main parameters of the wireless charging
transmitter (WCT) are as follows:
•The input voltage ranges from 9 V DC to
16 V DC (automotive bat range).
•The input voltage can drop down to 6 V
DC level during the start-stop function.
•The nominal delivered power to the
receiver is 15 W (at the output of the
receiver) and can be compatible with 5W
receiver.
•Designed to meet the Qi 1.2.3
specification.
•Operation frequency: 125 kHz for Qi
devices.

2.2 Board description
The WCT board is connected to the system by the main power connector. It comprises the automotive
battery connection (red wire = +12 V line, black wire = GND line), the CAN connection (yellow wires),
and the IGNITION (blue wire).
The connectors on the bottom edge of the board provide a JTAG connection for programming and
debugging, 2xSCI for the FreeMASTER tool connection for the debug option and the console connection,
and the temperature connector and backup touch sense connector are placed on the edge of the board. The
thermal resistor circuits can be used to develop the temperature sensing and protection.
The circuitryon the board is covered by the metal shield to lower the EMI and provides a fixed position for
the coils. Figure 2 shows the device.

2.4 Hardware setup for FreeMASTER and Console communication
To set up the hardware for FreeMASTER and Console communication, perform the following steps:
1. Find two UART-to-USB adaptor boards, and successfully install this UART-to-USB device driver
on the computer. The virtual serial port on the computer should work well.
2. Plug the USB-UART converting board to SCI connector J2 according to the SCH signal pin
position. The two channels of UART are for different purposes: FreeMASTER and Console.
