Wireless Power Design Kit – Medium Power

Order Code: 760308MP, Version 1.0

Transmitter Module, Receiver Module and LED Load Module compliant to Qi v1.2.2

● Abstract

ROHM Semiconductor and Würth Elektronik (WE)

offers this wireless power design kit (order code

760308MP) to demonstrate the advantages of

wireless power and to give developers the opportunity

to test and integrate a wireless power solution into

their application.

This design kit is based on the Qi specification 1.2.2

and supports the Extended Power Profile (EPP) from

the Wireless Power Consortium (WPC). Receiver and

transmitter are also backwards compatible with the

low power mode (Baseline Power Profile).

This manual describes the setup and basic usage of

this design kit.

● Description of Featured Products

The BD57020MWV is an IC for wireless power

transmitter applications. This device is composed of

pre-driver inverters for the TX coil, Qi compliant

controller for the communication and demodulating

circuit, GPIO, XO buffer, and I2C interface. The

BD57020MWV works as an analog frontend driven by

a general-purpose microcontroller. In this design kit

the transmitter is controlled by the MCU

ML610Q772-B03, which has all necessary firmware

to be compliant with the WPC Qi ver.1.2.2 standard

and supports wireless power transmission up to 15W.

BD57015GWL is a wireless power receiver IC. The

device integrates a fully synchronous rectifier circuit

with low-impedance FETs, Qi and PMA compliant

packet controller, adjustable regulated voltage output,

and an open-drain output terminal to communicate

with the power transmitter using amplitude

modulation. The BD57015GWL is targeted at mobile

applications implementing wireless charging

compliant to Qi Medium Power (including Low Power)

and PMA standard. For further details, please also

Wireless Power Design Kit – Medium Power – 760308MP V1.0 Design Kit Manual 1. Introduction WPC's Qi standard for medium power has attracted attention as a next-generation standard for inductive power transmission that will enable wireless charging of tablet PCs while allowing smartphones and other mobile devices to be charged up to three times faster than the existing low power standard (5W).

Wireless Power Design Kit – Medium Power – 760308MP V1.0 Design Kit Manual The MCU on the receiver side is required for the proper configuration of the RX IC. Without the configuration the RX is not sending the needed parameters during the negotiation/calibration phase to enable the medium power transfer mode. The I2C interface is used to set the necessary parameters such as the LDO output voltage, the current limit, FOD and QFOD settings.

Design Kit Setup and Operating Instructions 3.1 Warnings       This design kit must only be operated by trained professionals. This design kit should be operated in a well ventilated environment and, if used inside a case, the case should not be covered. This design kit should be placed on a stable, flat, non-conductive surface in use and should not be contacted by conductive items.

Wireless Power Design Kit – Medium Power – 760308MP V1.0 Design Kit Manual 3.4 Transmitter (TX) Module When power is provided to the TX Module at CONN1, LED1 will light green to indicate presence of the 19V input voltage. Additionally LED2 will light green when the 5V DC/DC converter has started up. The Transmitter Module is now in low power “idle” mode where it is periodically pinging on the wireless interface to detect presence of a receiver device.

When Sw1 is turned on (default setting) the LED driver is enabled and the LED matrix on the top side will light. Turning Sw2 off will disable the LED matrix load. In this case a user defined load may be attached between VOUT and GND as indicated in Figure 7.
