General Description
The MAX4995A/MAX4995AF/MAX4995AL/MAX4995B/
MAX4995C programmable current-limit switches fea-
ture internal current limiting to prevent damage to host
devices due to faulty load conditions. These analog
switches feature a low 130m?(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/out-
put) 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癈 to
+125癈 extended temperature range.
