SLVS608 – JANUARY 2006
Figure 4. Whole Operation Sequence Chart
TPS65560 has one internal enable latch, F1, that holds the charge enable (ON/OFF status) of the device. See
The only way to start charging is to input CHG
↑ (see time A/C/H in Figure 4). Each time CHG↑ is applied, the
TPS65560 starts charging.
There are three trigger events to stop charging:
1. Forced stop by inputting CHG = L from the controller (see timeB in Figure 4).
2. Automatic stop by detecting a full charge. VOUT reaches the target value (see TimeD in Figure 4).
3. Protected stop by detecting an over current function (OVDS) trigger at SW pin (see TimeI in Figure 4).
When the charging operation is complete, the TPS65560 drives the charge completion indicator pin, XFULL, to
GND. A controller can detect the status of the device as a logic signal when connected through a pullup resister,
R1 (see Figure 1).
The XFULL output enables the controller to detect the OVDS protection status. If OVDS protection occurs, XFULL
never goes L during CHG = H. Therefore, the controller detects OVDS protection by measuring the time from
CHG high to XFULL low. If the time to XFULL low is longer than the maximum designed charge time, then an
OVDS protection occurred.
The device starts charging at timeH, and OVDS protection occurs at TimeI (see Figure 4). At TimeI, XFULL stays
H. At TimeJ, the controller detects OVDS protection through the expiration of a timer ends and then sets CHG to
low to terminate the operation.
