(1) Current fault indication will be active. Current fault auto recovery will be de-activated.
(2) If operating continuously with this current limit, ensure that the current through the device does not cause the TJ to be greater than T(SDN) for a given ambient temperature and thermal property of the system. For pulse durations t < 200 µs, the device can source or sink current of at least 500 mA across the recommended operating conditions.
