Additional Details

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 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.

The MAX14523A/MAX14523AL/MAX14523B/MAX14523C are available in a tiny 8-pin, 3mm x 3mm, TDFN package and operate over the -40°C to +125°C automotive temperature range.
