GENERAL 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 the 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
