bq501210 bqTESLA™ Wireless Power TX EVM

NOTE:

Status LED behavior is controlled by LED mode resistor R9, 42.4 k

Ω

for mode 1. See the

bq501210 data sheet for additional options and configurations of LEDs D6, D7, and D8.

Start Up Receiver Placed on Transmitter

The transmitter sends a digital ping about every 500 ms. If a receiver is present, it powers up and replies,
then begins the power transfer.

is a scope capture of the bq501210EVM-756 beginning a power

transfer with the 15-W RX.

Figure 11. Start Up

The bq501210 device supports 2-way communication between the receiver and transmitter. All
communication between the TX and RX is initiated by the RX. The TX will respond as appropriate.

shows the activity of the request and response during the startup phase. The TX_COMM (TP13)

is a test point that shows the simplified information sent from the TX to the RX following the WPC v1.2 2-
way communication protocol. See the WPC v1.2 specification for details on the communication protocol.
