                High-Current Over-Voltage Protector
                 
                High-Current Over-Voltage Protector
                GENERAL DESCRIPTION

                The SGM40653/4/5 over-voltage protection devices feature a low 62mΩ (TYP, CSP package)/73mΩ (TYP, TDFN package) RON internal FET and protect low-voltage systems against voltage faults up to +28VDC. An internal clamp also protects the devices from surges up to +120V. When the input voltage exceeds the over-voltage threshold, the internal FET is turned off to prevent damage to the protected downstream components.

                The over-voltage protection threshold can be adjusted with optional external resistors to any voltage between 4V and 20V. If the OVLO input is below the external OVLO select voltage, the SGM40653/4/5 automatically choose the internal trip thresholds. The internal over-voltage thresholds (VIN_OVLO) are preset to be 15.39V/6.8V/5.81V typical (SGM40653/4/5). The devices feature an open-drain  ACOK  output indicating a stable supply between minimum supply voltage and VOVLO. The SGM40653/4/5 are also protected against over-current events by an internal thermal shutdown. The SGM40653/4/5 also have enable control to reduce power consumption.

                The SGM40653/4/5 are available in Green TDFN-3×3-12L and WLCSP-1.30×1.83-12B packages, and operate over an ambient temperature range of -40 to +85.
