GENERAL DESCRIPTION
The MAX14523A/MAX14523AL/MAX14523B/MAX14523C programmable current-limit switches feature internal current limiting to prevent damage to host devices due to faulty load conditions. These current-limit switches feature a low 70mΩ on-resistance and operate from a +1.7V to +5.5V input voltage range. The current limit is adjustable from 250mA to 1.5A, making these devices ideal for SDIO (secure digital input/output) and other load-switching applications. 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 Additional safety features include thermal shutdown to prevent overheating and reverse-current blocking to prevent current from being driven back into the source. ♦ Adjustable Current-Limit Threshold ♦ Low-Dropout Voltage (70mV at 1A Load Current) ♦ Short-Circuit Protection ♦ Thermal-Shutdown Protection ♦ Reverse-Current Protecti...
