The MAX14699 overvoltage protection (OVP) device features a low 38mΩ (typ) on-resistance (RON) internal FET and protects low-voltage systems against voltage faults up to +28VDC. An internal clamp also protects the device from surges up to +100V. The MAX14699 features a 100ns (typ) overvoltage response time to minimize voltage rise on OUT during an overvoltage event. When the input voltage exceeds the overvoltage threshold, the internal FET is quickly turned off to prevent damage to the protected downstream components.

The overvoltage protection threshold can be adjusted with optional external resistors to any voltage between 4V and 20V. With the OVLO input set below the external OVLO select voltage, the MAX14699 automatically selects the accurate internal trip threshold. The internal over voltage threshold (OVLO) is preset to 13.75V (typ). The device features an open-drain active-low ACOK output, indicating a stable supply between minimum supply voltage and VOVLO. The MAX14699 is protected against overcurrent events by an internal thermal shutdown.

The MAX14699 is offered in a small, 12-bump WLP package and operates over the -40°C to +85°C extended temperature range.
