描述 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 50mA 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 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 (nACOK) 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.
