  • Wireless power Tx to Tx conflict and protection
    Patent number: 11909220
    Abstract: A wireless power device is presented that avoids transmit conflicts. The device can include a rectifier circuit coupled to a coil; a transmit driver coupled to the rectifier circuit; a transmit detect circuit configured to detect receipt of transmitted wireless power at the coil; and a controller coupled to the transmit driver and the transmit detect circuit, the controller receiving a signal from the transmit detect circuit and providing an alert of the presence of the transmitted wireless power, the controller activating the transmit driver to transmit wireless power in absence of the signal. The wireless device can determine an operating mode and in a transmit mode determine presence of a received power. If received power is detected an alert can be provided and an off state initiated. If transmit power is not detected the transmit driver can be activated.
