Start/Stop Charging
TPS65552A has one internal enable latch, F1, that holds a charge
(ON/OFF
status) of the device. See
Figure 2
.
The only way to
start
charging is to input CHG
↑
(see time A/C/H in
Figure 4
). Each time CHG
↑
is reached, the
TPS65552A starts charging.
Indicate Charging Status
When the charging operation is completed, the TPS65552A drives the charge completion indicator pin, XFULL,
to GND. XFULL is an open-drain type output. When connecting the indicator LED to XFULL, the LED lights are
on when fully charged. The controller detects the status of the device as a logic signal when connecting a pullup
resister, R1 (see
Figure 1
).

Figure 4. Whole Operation Sequence Chart
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 full charge. VOUT reaches the target value (see TimeD in
Figure 4
).
3. Protected
stop
by over V
DS
detection (see TimeI in
Figure 4
).
XFULL enables the controller to detect the over V
protection status using software time. If over V
protection
occurs, XFULL never goes L during CHG = H, provided that the timer that starts at CHG
↑
stops at XFULL
↑
, and
times out within a designed period of maximum charging times. The controller can detect over V
DS
at time out.
The device starts charging at
timeH
, and over V
protection occurs at TimeI (see
Figure 4
). At timeI, XFULL
stays H, and the controller detects over V
DS
protection when the timer ends at timeJ. In this event, the controller
inputs CHG = L to terminate the operation.
