The MAX14575AETA+T 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 32mI (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 these devices ideal for charging a large load capacitor as well as for high-current load switching applications. Each device in the family handles an over current event differently depending on the option selected. The MAX14575AETA+T feature an auto retry mode, the MAX14575AETA+T has active high. Additional safety features include thermal shutdown protection to prevent overheating and reverse current blocking to prevent current from being driven back into the source. The MAX14575AETA+T is available in a small 8-pin, 2mm x 2mm TDFN package and operate over the -40°C to +85°C extended temperature range.
