MAX4785 - 50mA/100mA Current-Limit Switches

General Description

The MAX4785

MAX4788 family of switches feature 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.

19-2664; Rev 1; 4/03 50mA/100mA Current-Limit Switches General Description The MAX4785–MAX4788 family of switches feature 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. They are available with guaranteed 50mA and 100mA current limits, making them ideal for load-switching applications. 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 MAX4785 and MAX4787 enter a latch-off state where the switch is turned off and FLAG is issued to the microprocessor.
