TPS65552A
SLVS567–JULY 2005
When TPS65552A overheats, all functions stop. The only way to recover is to wait for the TPS65552A to cool
down. This protection is not through
SHUTDOWN
, so the TPS65552A restarts charging if CHG stays H during
the whole overheated period.
To prevent a condition such as pulling current from a poor power source (i.e., an almost empty battery), the
TPS65552A provides a maximum
ON
time protection. If the
ON
time exceeds t
MAX
, the TPS555x is forced
OFF
regardless of I
(PEAK)
detection.
To avoid the stress of power dissipation, the TPS65552A provides an overvoltage monitor function at the SW
terminal. If this protection occurs, the overvoltage status is latched (see
Figure 4
and its descriptions).
This function also protects short-circuit of the secondary side. In the short-circuit state of the secondary side,
almost 100% of the battery voltage is supplied to SW, which stresses the device.
