SGM40663/SGM40664/SGM40665/SGM40666/SGM40667/SGM40668 High-Current Over-Voltage Protector

PublishTime：2020-09-14

The SGM40663/4/5/6/7/8 are over-voltage protection devices designed to protect low voltage systems from damage with a high voltage supply that up to +30VDC and+40VPEAK (10s with 50mA current limit). It can also withstand surges up to +110V/-400V without damage.
The integrated 28mΩ (TYP) RON FET allows it to path 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 voltage (0.27V TYP), the SGM40663/4/5/6/7/8 automatically choose the internal trip thresholds that preset to be 22.2V/15.3V/10.5V/6.83V/6.35V/5.95V typical.
The open-drain nACOK output indicates a stable power supply between minimum supply voltage and VOVLO.
The SGM40663/4/5/6/7/8 are available in a Green WLCSP-1.17×1.63-12B package.
