Abstract
This manual describes how to use the NXQ1TXH5DB1355 board in
combination with a NXQ1TXH5 design. The document describes how to
connect the NXQ1TXH5DB1355 board to a PC and the NXQ1TXH5. This
enables engineers to verify operation of the NXQ1TXH5 in a customer
specific design. This eases the design of a wireless power transmitter using
the NXQ1TXH5.

Page 3: Introduction
Introduction This document describes how to use the NXQ1TXH5DB1355 plugin board. The NXQ1TXH5DB1355 board can be used in combination with the NXQ1TXH5DB1401 demo board or with a customer-specific design. The NXQ1TXH5DB1355 plugin board contains a microcontroller, the LPC824M201JDH20. This microcontroller interfaces between the I C from the NXQ1TXH5 and the UART. -
Page 4: Nxq1Txh5Db1355 Board Connections
Connect the SDA, SCL, and GND pins of header X3 to the design with the NXQ1TXH5. To power the components on the NXQ1TXH5DB1355 board, connect a 5 V supply to pin 9 and its GND connection. This supply can be obtained from a separate lab supply or from the NXQ1TXH5 application. - Page 5 UM11152 NXP Semiconductors NXQ1TXH5DB1355 plugin board Table 2.

Page 9: Commands And Messages
Commands and messages This chapter explains the two commands that can be sent from a terminal to the NXQ1TXH5DB1355 board and the response to those two commands. 4.1 Version The values that are shown after typing "version" can be used to verify if the correct parameters are set with the configuration resistors. -
Page 10: Log
4.2 log The log command is used to toggle the logging on and off. When the logging is on, the NXQ1TXH5DB1355 board sends the commands which are explained below to the terminal. The number at the beginning of each line is the timestamp. It is the time (in msec) that has passed since the receiver was placed on the charger. - Page 11 UM11152 NXP Semiconductors NXQ1TXH5DB1355 plugin board When the receiver is placed on the charger, it sends the values for the "maximum power value" and "power class" to the charger in the configuration packet (0x51). In practice, "Power Class" is 0 and the "Maximum power value" is 10 so the RPP value must be multiplied with 39.06 mW to get the value for prx.

NXP Semiconductors NXQ1TXH5DB1355 plugin board Schematic Figure 8 shows the schematic of the NXQ1TXH5DB1355 board. It contains an LDO to create the 3.3 V supply voltage for the LPC824 microcontroller and the pull-up resistor of the I C connection. Header X4 exposes a UART connection to the FTDI cable to connect to the PC. -
