The MAX4826MAX4831 family of switches has internal current limiting to prevent host devices from being damaged due to faulty load conditions. These analog switches have a low 0.7 on-resistance and operate from a +2.3V to +5.5V input voltage range. These devices are available with guaranteed 50mA and 100mA current limits, making them ideal for loadswitching applications. In addition to the current-limit fault flag (FFLG), an open-drain no-load flag indicator (NOLD) notifies the system when the current through the switch is less than 10mA (MAX4826MAX4829), or 5mA (MAX4830/MAX4831).
