Battery Charge Current Output.
This pin provides charge current to the battery and
regulates the final float voltage to 4.2 or 8.4V. An internal
precision resistor divider from this pin sets the float voltage
which is disconnected in shutdown mode.
9(Exposed Pad) PGND
Exposed Pad Should be soldered to PCB Board and
Connected to GND.
Note: LP28007-42MSF and LP28007-84MSF of Battery (Pin8) is output pin, the pin connects to Battery.
