MAXIM MAX4987AEETA+T

The MAX4987AE are overvoltage protection devices with integrated ESD protection for USB data lines. These devices feature a low R o N internal FET and protect low-voltage systems against voltage faults up to +28V. If the input voltage exceeds the overvoltage threshold, the internal nFET switch is turned off to prevent damage to the protected components. The 30ms debounce time prevents false turn-on of the internal nFET switch during startup. An open-drain active-low logic output is available to signal that a successful power-up has occurred.
