FUNCTIONAL HOLDING CURRENT (IH) TEST CIRCUIT : GO-NO GO TEST
LCP1521
R
Surge generator
VBAT = - 100V
D.U.T
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, 10/1000µs.
- The D.U.T. will come back to the off-state within a duration of 50ms max.
