Apple 7.5W wireless charging scheme bqt008

The company has been developing wireless charging schemes since 2013
Bqt008 is perfectly compatible with 7
5W, 10W and 5W solutions
The bqt008 master controller is also a 7100 single coil scheme and a 3200 dual coil scheme
This scheme has the characteristics of fast, stable, beautiful and high cost performance: fast: fast adaptation, fastest update, automatic adjustment of fixed frequency and frequency conversion, and the highest efficiency
Both Apple 7
5W and Samsung 8W can be charged quickly
Stable: stable operation, continuous charging, no burning, stable supply of goods
Beauty: perfect compatibility
All built-in mobile phones can be charged
5v1a, qc2
0 and dc9v can be used as power input
It also has the following advantages:   1
9V direct input, no dc/dc power supply, few components and high efficiency 2
0
2% high-precision oscillation is integrated internally without adding 8m crystal 3
Support USB update and upgrade 4
All schemes can pass Qi 1
2 certification 5
The supporting MOS, capacitors and magnetic discs all have a awesome ecological chain
There is no shortage or price increase 6
The overall scheme is very cost-effective, and the BOM cost can reach about 14
Perfect protection measures: 1
Overvoltage protection: when the input voltage exceeds 10 V, the indicator will prompt an error and stop the power transmission
2
Overcurrent protection: double protection   a
0
if the current exceeds 2a for 1 second, the power supply will be turned off   b
If the current exceeds 4A for 0
5 seconds, the fuse will be blown to prevent more serious accidents
3
Over temperature protection: power operation will be limited at 55 ℃
When the temperature exceeds 60 ℃, an error will be prompted and the power will be turned off for 10 minutes
4
Fod: in standby mode, if foreign matters are found, an error will be prompted; When working, if the efficiency is found to be low, an error will be prompted and the power will be turned off for 10 minutes;
