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. Figure 8.
