STGAP2SCMTR
STGAP2SCMTR ST: During use, an issue has been identified. When the primary-side signal is 0 V, the secondary-side signal turns on spontaneously for approximately 500 ns. What is the cause of this?
Symptoms: With the primary-side signal at 0 V (in the off state), the secondary side switches off normally under the influence of a low dv/dt (approximately 30 V/ns); however, under the influence of a dv/dt of approximately 60 V/ns, the secondary side switches on spontaneously for approximately 500 ns. The chip is rated at 100 V/ns;
