7 / 8 page 7 EVBD4400 FLT Reset Vcc Vcc (From FLT)(n.h.) 10K 10K .01uF .01uF To Eval bd INH To Eval bd INL INH INL 1 2 3 4 5 6 9 10 8 12 13 11 1 2 34 74HC00 1/4 74HC00 2/4 74HC00 3/4 74HC00 4/4 74HC04 1/6 74HC04 2/6 In Figures 4 & 5, the schematic assumes the de- signer will be using some type of external control system for starting the circuit and/or reseting the circuit in the event a fault occures. As an alternative, Figure 6 demonstrates a simple and inexpensive Start/Reset logic circuit for manually implementing fault protection. With the addition of High Current MOSFET Drivers on the outputs, the IXBD4410/11's typical 2A Peak Output Current capability can be "boosted" to drive the latest IXYS MOSFETS & IGBT's. Figure 6: Simple Fault Protection Logic Circuit Figure 6 shows the addition of two IXDD414's. These are CMOS high-speed MOSFET drivers that have a 14A Peak Output Drive Capability, allowing the 4410/11 chipset to drive a pair of IXFK90N20Q 90A/ 200V Power Mosfets. (The 2 ohm gate resistors shown should be Non-Inductive High Performance Film resistors such at those available from Caddock. Par- ticular attention also needs to be paid to Suppy By- passing, Grounding, and minimizing the Output Lead Inductance when designing such a high power circuit layout). |
