Introduction

The EVBD4400 evaluation board implements a single power phaseleg circuit on a double sided PCB with ground plane, using the proven ISOSMARTTM 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.

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.
