Introduction

The MAX14586/MAX14590 overvoltage protection devices feature a low 48mΩ (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 internal accurate trip thresholds. The internal overvoltage thresholds (OVLO) are preset to 7V typical (MAX14586) or 15V typical (MAX14590). The devices are also protected against overcurrent events by an internal thermal shutdown. The MAX14586/MAX14590 are offered in a small, 8-pin TDFN package with exposed pad and operate over the -40°C to +85°C extended temperature range.
