SGM40657/SGM40658 High-Current Over-Voltage Protector
GENERAL DESCRIPTION
The SGM40657/8 over-voltage protection devices feature a low 20mΩ (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. If the OVLO input is below the external OVLO select voltage, the SGM40657/8 automatically choose the internal trip thresholds....
