... Each device in the family handles an overcurrent event differently depending on the option selected. The MAX14523A/MAX14523AL go into an autoretry mode, the MAX14523B latches off the switch, and the MAX14523C features a continuous current-limit mode. Additional safety features include thermal shutdown to prevent overheating and reverse-current blocking to prevent current from being driven back into the source ...
