SGM40669 - High-Current Over-Voltage Protector

Download the SGM40669 datasheet PDF. This datasheet also covers the SGM40663 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.

Description

The SGM40663/4/5/6/8/9 are over-voltage protection devices designed to protect low voltage systems from damage with a high voltage supply up to +31VDC and +40VPEAK (10s with 50mA current limit).

They can also withstand surges up to +110V/-400V without damage.

Features

  • Wide Power Supply Voltage Range: 2.5V to 28V.
  • Input Voltage up to 40V with 50mA Current Limit for 10s Duration.
  • Integrated Switch On-Resistance: 28mΩ (TYP).
  • Wide Adjustable OVLO Threshold Range: 4V to 22V.
  • Internal Over-Voltage Protection Thresholds: 22.2V (TYP) (SGM40663) 15.3V (TYP) (SGM40664) 10.5V (TYP) (SGM40665) 6.83V (TYP) (SGM40666) 5.95V (TYP) (SGM40668) 6.35V (TYP) (SGM40669).
  • Up to +110V/-400V Surge Immunity.
  • Over-Voltage Shutdown Response: 50ns (TY.

SGM40663/SGM40664/SGM40665 SGM40666/SGM40668/SGM40669 High-Current Over-Voltage Protector GENERAL DESCRIPTION The SGM40663/4/5/6/8/9 are over-voltage protection devices designed to protect low voltage systems from damage with a high voltage supply up to +31VDC and +40VPEAK (10s with 50mA current limit). They can also withstand surges up to +110V/-400V without damage. The integrated 28mΩ (TYP) RON FET allows it to pass through 4.5A continuous current. The FET is turned off when the input voltage exceeds the over-voltage threshold, which can be adjusted between 4V and 22V with the optional external resistors. When the OVLO input is set below the external OVLO select threshold (0.27V TYP), the SGM40663/4/5/6/8/9 automatically choose the internal trip thresholds that are preset to 22.2V/15.
