VOUT Selection - Device with VBO < 200 Volt - V OUT = 250 VRMS, R1 = 140 Ω. - Device with VBO ≥ 200 Volt - VOUT = 480 V RMS, R2 = 240 Ω. FUNCTIONAL HOLDING CURRENT (IH ) TEST CIRCUIT 2. R D.U.T. - VP VBAT = - 48 V Surge generator This is a GO-NOGO Test which allows to confirm the holding current (IH ) level in a functional test circuit. TEST PROCEDURE : 1) Adjust the current level at the IH value by short circuiting the AK of the D.U.T. 2) Fire the D.U.T with a surge Current : Ipp = 10A , 10/1000 µs. 3) The D.U.T will come back off-state within 50 ms max. 4/7 THBT200S APPLICATION CIRCUIT Typical line card protection concept RING GENERATOR - Vbat PTC LINE A TIP T E S T RING RELAY R E L A Y S LINE B SLIC RING PTC THBT200S THDTxxx or LCPxxx FUNCTIONAL DESCRIPTION Line A Tip LINE A AND LINE B PROTECTION.
