The MAX14575CETA+T from Maxim Integrated Products is a 250mA to 2.5A adjustable current limit switch in 8 pin TDFN package. This programmable current-limit switch features internal current limiting to prevent damage to host devices due to faulty load conditions. It features a low 32mohm (typ) on-resistance and operate from a +2.3V to +5.5V input voltage range. The current limit is adjustable from 250mA to 2.5A making this device ideal for charging a large load capacitor as well as for high current load switching applications. The safety features include thermal shutdown protection to prevent overheating and reverse current blocking to prevent current from being driven back into the source. Typical applications include RF power amplifier in cell phones, USB ports, data modem cards, portable media players, UTCA/ATCA platforms and SDXC card power-supply protection.
