SGM40669 Datasheet | SG Micro

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 50m A 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/15.3V/10.5V/6.83V/5.95V/6.35V typically. The open-drain output (n ACOK) indicates a stable power supply between minimum VIN and VOVLO. The SGM40663/4/5/6/8/9 are available in a Green WLCSP-1.17×1.63-12B package.
