An example of battery charger can be:
NOTE: In this particular application the battery charger input current must be limited to less than 1A. Using a
current limited wall adapter as the power source can do this.
For your convenience in the EVK there's also a current unlimited input, where the input source is not limited in
current and the drawn current is limited to about 0,5A by a MOSFET in the EVK.
The external battery charger is suggested in applications where the total consumption is higher than the current
provided by the GM862-QUAD / PY module.
