8.4 Device Functional Modes

The operational modes of the BQ51013C-Q1 are described in the Section 8.3. The BQ51013C-Q1 has several functional modes. Start-up refers to the initial power transfer and communication between the receiver (BQ51013C-Q1 circuit) and the transmitter. Power transfer refers to any time that the TX and RX are communicating and power is being delivered from the TX to the RX. Power transfer termination occurs when the RX is removed from the TX, power is removed from the TX, or the RX requests power transfer termination.
