8.7.2 Overcurrent Conditions (TPS2061, TPS2062, TPS2065, and TPS2066)

Three possible overload conditions can occur for the TPS2061, TPS2062, TPS2065 and TPS2066. In the first condition, the output has been shorted before the device is enabled or before VI(IN) has been applied (see Figure 6-15 through Figure 6-18). The TPS20xx senses the short and immediately switches into a constant-current output.

In the second condition, a short or an overload occurs while the device is enabled. At the instant the overload occurs, high currents may flow for a short period of time before the current-limit circuit can react. After the short-circuit output current threshold (IOS) is reached, the device switches into constant-current mode.

In the third condition, the load has been gradually increased beyond the recommended operating current. After the short-circuit output current threshold (IOS) is reached, the device switches into constant-current mode.
