TEST CIRCUIT 2 for IH parameter.
SMP100-xxx
R
VBAT = - 48 V
D.U.T.
- VP
Surge generator
This is a GO-NO GO test which allows to confirm the holding current (IH) level in a functional test circuit.
TEST PROCEDURE :
- Adjust the current level at the IH value by short circuiting the D.U.T.
- Fire the D.U.T. with a surge current : Ipp = 10A, 10/1000 µs.
- The D.U.T. will come back to the off-state within 50 ms max.
