MAX4842 Overview
The MAX4838 MAX4842 are overvoltage protection ICs that protect low-voltage systems against voltages of up to 28V. If the input voltage exceeds the overvoltage trip level, the MAX4838 MAX4842 turn off the low-cost external n-channel FET(s) to prevent damage to the protected ponents. An internal charge pump eliminates the need for external capacitors and drives the FET gate for a simple, robust solution.
