ADVANCED DATASHEET SGM40656/SGM40657/SGM40658 High-Current Over-Voltage Protector Upgrade Replacement to - 14653/4/5 GENERAL DESCRIPTION The SGM40656/7/8 over-voltage protection devices feature a low 25mΩ (TYP) 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 ponents. The over-voltage 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...
