Quick Start Procedures
The Evaluation Board is fully assembled and tested. Follow the steps below to verify board operation. Do not turn on
supplies until all connections are made.
Proper measurement equipment setup and follow the procedure below.
1. Set power source equal 3.8V/5A then connect to BAT and GND of EVB.
2. Use E-Load connect to power source and enable CC loading from power source.
3. The AP connect to SCL, SDA and GND of EVB

4. Check I C can work normally by connecting to slave address (0x53).
5. Set VBUS = 5V/3A and connect to VBUS and GND of EVB.
6. Check have charging current to
Check 0x0F[3:0] shows '0100' (Fast-charge)
