The MAX4995A/MAX4995AF/MAX4995AL/MAX4995B/MAX4995C programmable current-limit switches feature internal current limiting to prevent damage to host devices due to faulty load conditions. These analog switches feature a low 130mΩ (typ) on-resistance and operate from a +1.7V to +5.5V input voltage range. The current limit is adjustable from 50mA to 600mA, 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 MAX4995A/MAX4995AF/MAX4995AL go into an autoretry mode, the MAX4995B latches off the switch, and the MAX4995C places the device in 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 MAX4995A/MAX4995AF/MAX4995AL/MAX4995B/MAX4995C are available in a tiny 10-pin, 1.4mm x 1.8mm UTQFN, a 6-pin SOT23, or an 8-pin, 2mm x 2mm TDFN package and operate over the -40°C to +125°C extended temperature range.
