7.7.1 Overcurrent Conditions (TPS2062-1 and TPS2065-1)

Three possible overload conditions can occur for the TPS2062-1 and TPS2065-1. In the first condition, the output has been shorted before the device is enabled or before VI(IN) has been applied (see Figure 6-6 through Figure 6-9). The TPS2062-1 and TPS2065-1 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 current-limit circuit has tripped (reached the overcurrent trip threshold (IOC)), the device switches into constant-current mode and current is limited at the short-circuit output current threshold (IOS).

In the third condition, the load has been gradually increased beyond the recommended operating current. The current is permitted to rise until the overcurrent trip threshold (IOC) is reached or until the thermal limit of the device is exceeded. The TPS2062-1 and TPS2065-1 are capable of delivering current up to the current-limit threshold without damaging the device. Once the overcurrent trip threshold (IOC) has been reached, the device switches into the constant-current mode current is limited at the short-circuit output current threshold (IOS).
