大电流过压保护器IC
The SGM40653/4/5 are over-voltage protection devices designed to protect low voltage systems from damage with a high voltage supply up to +28VDC. The SGM40653/4/5 can withstand surges up to +120V without damage.
The integrated 62mΩ (TYP, CSP package)/73mΩ (TYP, TDFN package) RON FET allow 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 20V with optional external resistors.
If the OVLO input is set below the external OVLO select threshold, the SGM40653/4/5 automatically choose the internal trip thresholds that are preset to 15.39V/6.8V/5.81V (SGM40653/4/5) typically.
The open-drain ACOK output indicates a stable power supply between minimum supply voltage and VOVLO. The SGM40653/4/5 also have enable control to reduce power consumption.
The SGM40653/4/5 are available in Green TDFN-3×3-12L and WLCSP-1.30×1.83-12B packages, and operate over an ambient temperature range of -40℃ to +85℃.
