IRS20124S(PbF)
Note 1: Logic operational for VS equal to -8 V to 200 V. Logic state held for VS equal to -8 V to -VBS.
Recommended Operating Conditions
For proper operation, the device should be used within the recommended conditions. The Vs and COM
offset ratings are tested with all supplies biased at a 15 V differential.
