ИС переключателя электропитания – распределение электропитания MAX14523CATA+T

Переключатель нагрузки , высокой стороны, активный высокий, 1 выход, 5.5В, 1.5А, 0.07Ом, TDFN-8

The MAX14523CATA+T from Maxim Integrated Products is a 250mA to 1.5A, adjustable current limit switch in 8 pin TDFN package. It features internal current limiting to prevent damage to host devices due to faulty load conditions. It feature a 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. 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. It is typically used in SDIO ports, USB ports, notebook VGA ports, GPS, cell phones, MP3 players and UTCA/ATCA platforms.
