MAX4826
Description
The MAX4826- MAX4831 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 0.7Ω on-resistance and operate from a +2.3V to +5.5V input voltage range. These devices are available with guaranteed 50m A and 100m A 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 10m A (MAX4826- MAX4829), or 5m A (MAX4830/MAX4831). When the switch is on and a load is connected to the port, a guaranteed blanking time of 14ms ensures that the transient voltages settle down. If, after this blanking time, the load current is greater than the current limit, the MAX4826/MAX4828/MAX4830 enter a latch-off state where the switch is turned off, and FFLG is issued to the microprocessor. The switch can be turned on again by cycling...
