SGM40666AS
SGM40666AS is High-Current Over-Voltage Protector manufactured by SG Micro.
SGM40666AS/SGM40666BS High-Current Over-Voltage Protector
GENERAL DESCRIPTION
The SGM40666AS and SGM40666BS 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). The SGM40666AS withstands +90V/-400V while the SGM40666BS can also withstand surges up to +80V/ -400V without damage.
The integrated 27mΩ (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...
