The OPA455 incorporates a status flag pin to indicate overcurrent or overtemperature conditions. This pin is an open-drain, active-low output that allows the pin to be easily interfaced with standard low-voltage logic. The pin goes active if the junction temperature of the device rises to greater than 150°C, and resets after the device cools to 130°C. Additionally, the pin goes active if the device attempts to source more than the maximum continuous current of 30 mA. The status flag can be monitored from TP2, and an external pullup voltage can be input on TP11.
