Features
· High to low side isolation of 1000V · Common-mode dv / dt immunity of greater than 50V / nanosecond · On-chip generated negative gate drive · Overcurrent protection by means of desaturation detection · Under voltage lockout · Fault indication output for system diagnostic · Optimized power circuit layout · High side bootstrap supply · Sockets for freewheeling fast recovery diodes (FREDS) · Flexibility of power level utilization · 5V compatible HCMOS input logic with hysterisis · Protection from cross conduction of the half bridge · Simple, fast and low cost means of evaluation and design · Option for using IXDP630 with RC oscillator or IXDP631 with crystal oscillator for improved dead time accuracy. · Three phase operation with the ability to attach additional slave driver boards.
Introduction
The EVBD4400 evaluation board implements a single power phaseleg circuit on a double sided PCB with ground plane, using the proven ISOSMART HALF BRIDGE DRIVER CHIPSET - IXBD4410, IXBD4411, IXDP630. The IXDP631 is optional. This board includes all parts required for the circuit implementation so that you can just follow the instructions in this document and connect the board to the load and power. The kit consists of an assembled and tested PCB with two power devices. Any power circuit is layout sensitive. The layout of this kit is a proven, working layout. The designer is invited to duplicate this layout in his system, following the evaluation of the driver chipset. Most systems vary in their power level requirements and therefore the power devices used. Due to this fact and fluctuations in availability of power devices, the kit will not always include the same power devices. The designer is encouraged to use the power devices that are required for his system. The devices that are enclosed serve only for initial evaluation.
