SGM40658 - High-Current Over-Voltage Protector

Download the SGM40658 datasheet PDF. This datasheet also covers the SGM40657 variant, as both devices belong to the same high-current over-voltage protector family and are provided as variant models within a single manufacturer datasheet.

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.

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 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 SGM40657/8 automatically choose the internal trip thresholds. The internal over-voltage thresholds (VIN_OVLO) are preset to be 6.82V/5.95V typical (SGM40657/8).
