TPS65552A
SLVS567 – JULY 2005
TPS65552A provides three protections: thermal shutdown, max on time, and overvoltage at power SW.
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 tMAX, 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.
