... If the load demands a current in excess the secondary limit, MIC2013 acts immediately to restrict output current to the secondary limit for the October 2005 duration of the Kickstart period. After this time the MIC2013 reverts to its normal current limit. An example of Kickstart operation is shown below. is the OUT is greater than V ...

Micrel Thermal Shutdown Thermal shutdown is MIC2003/2013 from damage should the die temperature exceed safe operating levels. Thermal shutdown shuts off the output MOSFET and asserts the FAULT/ output if the die temperature reaches 145°C. MIC2003/2013 will automatically resume operation ...

... During Kickstart a secondary current limiting circuit is monitoring output current to prevent damage to the MIC2013 hard short combined with a robust power supply can result in currents of many tens of amperes. This secondary current limit is nominally set at 4 Amps and reacts immediately and independently of the Kickstart period ...
