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 select threshold (0.26V TYP), the SGM40666AS and SGM40666BS automatically choose the internal trip thresholds that are preset to 6.79V typically. SGMICRO provides customized OVP threshold options for 22.2V/15.3V/10.5V/6.35V/5.95V. Please contact us if necessary.
The open-drain output (nACOK) indicates a stable power supply between minimum VIN and VOVLO. The SGM40666AS and SGM40666BS are available in a Green WLCSP-1.65×1.24-12B package.
