The LMZM33602 is protected from overcurrent conditions. Hiccup mode is activated if a fault condition persists to prevent overheating. In hiccup mode, the regulator is shut down and kept off for 10 ms typical before the LMZM33602 tries to start again. If overcurrent or short-circuit fault condition still exist, hiccup repeats until the fault condition is removed. Hiccup mode reduces power dissipation under severe overcurrent conditions, and prevents overheating and potential damage to the device. Once the fault is removed, the module automatically recovers and returns to normal operation as shown in Figure 7-16.
