P9242-R Transmitter Evaluation Board Transmitter Coil
P9221-R-EVK
Description
The P9242-R-EVK Mass-Market Evaluation Board demonstrates
the features of the P9242-R 15W Wireless Power Transmitter
(TX). It is intended to evaluate the functionality and performance
of the P9242-R when combined with a power receiver in a
wireless charging system. The P9242-R-EVK offers the flexibility
to select parameters, such as the over-current limit threshold,
LED pattern, and external temperature sensing function. The
printed circuit board (PCB) has four layers. The P9242-R
Evaluation Board is designed to function with the P9221-R
Receiver Evaluation Board, which is ordered separately. It can
also be used with the user’s WPC-1.2.2 compliant receiver.
The high-efficiency, turnkey reference design is supported by
comprehensive online, digital resources to significantly expedite
the design-in effort and enable rapid prototyping. The total active
area is optimized to 32mm x 32mm.

1. Setup
1.1 Required or Recommended User Equipment
The following additional lab equipment is required for using the kit:
P9221-R-EVK Receiver Evaluation Board or any WPC-1.2.2 compliant receiver
Power supply or 12V/2A AC adaptor
1.2 Kit Hardware Connections
Follow these procedures to set up the kit as shown in Figure 1.
1. Set up the P9242-R Evaluation Board: Plug the 12V adapter or user’s power supply into the J3 (barrel connector on the bottom of the
board) or J1 (micro USB connector).
2. Place the P9221-R-EVK or the user’s receiver on the transmitter (TX) pad with the components facing up as shown in Figure 1.
3. Verify that the two green LEDs identified in Figure 1 are illuminated indicating that coupling has been established.
4. If using the P9221-R-EVK Evaluation Board as the receiver, connect wires to the VOUT and GND test points on the P9221-R-EVK
receiver to measure the output voltage and apply a load.

2.2 LED Pattern Selection
The P9242-R-EVK uses two LEDs (LED1 and LED2; see Figure 2) to indicate the power transfer status, faults, and operating modes. The
LEDs are connected to the LED1 and LED2 pins as shown on P9242-R-EVK schematics (see section 3.1). The LED patterns can be selected
by setting the voltage on the LED_PAT pin through the resistor divider R43 and R44; see Table 1 for the options. On the evaluation board the
LED_PAT pin is pulled up to 3.3V through R43. R44 is unpopulated; therefore, option 7 is the default option.

2.3 Adjustment of Over-Current Limit
The over-current protection (OCP) is designed to protect the transmitter from operating conditions that could potentially cause damage or
unexpected behavior from the system. The input current is continuously monitored during the power transfer stage. If the input current goes
above the OCP threshold of the programmed current limit, the P9242-R will increase the switching frequency or reduce the duty cycle in order
to keep the input current below the OCP value. The current limit can be selected by setting the voltage on the ILIM pin through the resistor
divider R48 and R40. On the P9242-R-EVK, the ILIM pin is pulled up to 3.3V through R48. R40 is unpopulated; therefore, the current limit is
set to 2.3A.

2.4 External Temperature Sensing –TS
The P9242-R includes an optional temperature sense input pin, TS, used to monitor a remote temperature, such as for a coil or a battery
charger.
The TS pin voltage can be calculated by Equation 1.


  
Equation 1
Where NTC is the thermistor`s resistance (RTH1) and R20 is the pull-up resistor connected to the 3.3V supply voltage on the P9242-R
Evaluation Board. The over–temperature shutdown is triggered if the voltage on the TS pin is lower than 0.6V. The RTH1 is not populated on
the P9242-R Evaluation Board.
