End-of-charge current
When the charge voltage approaches the selected value (4.1 V or 4.2 V), the voltage
regulation phase takes place. The charge current starts to decrease until it goes lower than
a programmable end value, IENDTH, depending on an external resistor connected between
Equation 10
Figure 14.
IEND pin connection
Where KEND is 1050; and VMIN is 50 mV.
Typically, this current level is used to terminate the charge process. However, it is also
possible to disable the charge termination process based on this current level (Chapter 7.9
This pin is also used to monitor the charge current, because the current injected in REND is
proportional to ICHG. The voltage across REND can be used by a microcontroller to check the
charge status like a gas gauge.
