SGM40661 - Adjustable Over-Voltage Protection Switche

Download the SGM40661 datasheet PDF. This datasheet also covers the SGM40659 variant, as both devices belong to the same adjustable over-voltage protection switche family and are provided as variant models within a single manufacturer datasheet.

Description

The SGM40659/60/61 over-voltage protection devices feature a low 27mΩ (TYP) on-resistance high current integrated MOSFET which actively protect low-voltage systems against voltage supply faults up to +28VDC.

Features

  • Wide Input Voltage Range: 2.5V to 28V.
  • Up to 4A Current Capability.
  • Integrated 27mΩ (TYP) N-Channel MOSFET.
  • Fast OVP Turn-Off Response Time: 80ns.
  • Flexible Over-Voltage Protection Design.
  • Internal Preset OVLO Thresholds: Fixed 15.61V (SGM40659) Fixed 6.80V (SGM40660) Fixed 5.94V (SGM40661).
  • Wide Adjustable OVLO Threshold Range from 4V to 20V.
  • Surge Immunity up to +40V.
  • Auto-Enabled Switch with 15ms Debounce Time.
  • Under-Voltage (UVLO), Short-Circ.

SGM40659/SGM40660/SGM40661 Adjustable Over-Voltage Protection Switches GENERAL DESCRIPTION The SGM40659/60/61 over-voltage protection devices feature a low 27mΩ (TYP) on-resistance high current integrated MOSFET which actively protect low-voltage systems against voltage supply faults up to +28VDC. An input voltage exceeding the over-voltage threshold will cause the internal MOSFET to turn off, preventing excessive voltage from damaging downstream devices. When the OVLO input is connected to GND, the SGM40659/60/61 automatically choose the internal fixed OVLO threshold, preset to be typical 15.61V/ 6.80V/5.94V (SGM40659/60/61). The over-voltage protection threshold can be adjusted with optional external resistors to any voltage between 4V and 20V.
