SGM40653/SGM40654/SGM40655 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.
