Termination modes
resistor between the IEND pin and GND. When the charge current goes down to this value,
after a de-glitch time, the status pins notify that the charge process is complete. This de-
glitch time is expressed as:
Equation 13
However, the termination of the charger process depends on the status of the VPRE pin:
●
If the voltage at the VPRE pin is higher than 0.8 V, the charge process is actually
terminated when the charge current reaches IENDTH.
●
If the voltage at VPRE pin goes lower than 0.8 V, the charge process does not terminate,
and the charge current can go lower than IENDTH. The status pins notify the end-of-
charge as a fault condition, but the device continues the charge. When the TMAXCH is
elapsed, the charge process ends, and a fault condition is issued.
●
If the voltage on VPRE pin is lower than 0.8 V during the Pre-charge Phase, the device
sets the VPRETHDefault automatically.
●
If the voltage at the VPRE pin goes lower than 0.5 V (edge sensitive), the timer is reset,
both in pre-charge and in fast-charge phase.
