Three possible overload conditions can occur for TPS2065DBV. In the first condition, the output has been shorted before the device is enabled or before VI(IN) has been applied (see Figure 7-38 through Figure 7-41). 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.
