The MAX14523BATA+T from Maxim Integrated Products is a 250mA to 1.5A, adjustable current-limit switch in 8 TDFN package. It features internal current limiting to prevent damage to host device due to faulty load conditions and low 70mohm 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 device ideal for SDIO (secure digital input/output) and other load-switching applications. Safety features include thermal shutdown to prevent overheating and reverse-current blocking to prevent current from being driven back into the source. Typical applications include SDIO ports, USB ports, notebook VGA ports, GPS, cell phones, MP3 players and UTCA/ATCA platforms.
