The MAX14738/MAX14739 overvoltage protection devices feature a low 76mΩ (typ) on-resistance (RON) internal FET and protect low-voltage systems against voltage faults up to +36V. When the input voltage exceeds the overvoltage threshold, the internal FET is turned off to prevent damage to the protected 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 devices automatically choose the accurate internal trip thresholds. The internal overvoltage thresholds (OVLO) are preset to 6.8V (typ) (MAX14738) or 10V (typ) (MAX14739). The devices are also protected against overcurrent events by an internal thermal shutdown.
The MAX14738/MAX14739 are offered in a small, 6-bump 1.3mm x 0.9mm wafer-level package (WLP) with an exposed pad and operate over the -40°C to +85°C extended temperature range.
