Overcurrent sensors using external low-resistance sense resistors are fairly common. However, the members of a new family of ICs from Maxim feature an internal sensor resistor and a switch for disconnecting the load if the current limit is exceeded. The members of this IC family are listed in the table.
There are two sorts of overcurrent switches in the family. The types listed in the ‘Latching’ column store any occurrence of an overcurrent condition and indicate it at the FLAG output until they are switched off and then on again by a pulse on the ON input.
