EPT Generator
This block generates end power transfer packets with appropriate messages that are sent to the transmitter.
Table 3 shows packet information for the end power transfer packet.

See Table 4
On receiving the end power transfer packet, the transmitter removes the power signal within tterminate ms. Table 4
shows the various error messages sent during different conditions.

NOTE
End power transfer can be the first packet that is sent to the transmitter if an external
adapter is detected during the power-up routine.
Control Error Packet and Power Packet Generator
This block computes the control error and actual power for the control error packet and power packet messages
respectively. The control error is calculated as a percentage difference between the rectifier voltage measured at
VIN_DIV and the target or desired rectifier voltage (see Equation 1).
(1)
Where,
Vrect is the rectifier voltage that is measured VIN_DIV input pin.
Vdesired is the desired rectifier voltage that is dynamically selected depending on the BQ25046 output current
that is measured at the ISET_SCALE input pin.
The control error packet is transmitted every 32 ms or 250 ms depending on if the control error calculated was a
large error or a small error, respectively. Control error is identified as a large error if the percentage difference is
greater than 5% when the BQ25046 charge is not enabled (that is, BQ25046_EN1 = 1 BQ25046_EN2 = 1) or
greater than 20% when the BQ25046 charge is enabled (that is, BQ25046_EN1 = 1 BQ25046_EN2 = 0). The
maximum control error percentage is saturated to ±30%.
The actual power is calculated as a percentage relative to 5 W (see Equation 2). The maximum power that can
be sent is 100%.
(2)
Where,
Vrect is the rectifier voltage that is measured VIN_DIV input pin.
IOUT is the BQ25046 current output that is measured at the ISET_SCALE pin.
