The IXBD4410/IXBD4411 ISOSMART chipset is designed to control the gates of two Power MOSFETs or Power IGBTs that are connected in a half bridge (phase-leg) configuration for driving multiple-phase motors, or used in applications that require half-bridge power circuits. The IXBD4410/IXBD4411 is a full-feature chipset consisting of two 16-Pin DIP or SO devices interfaced and isolated by two small-signal ferrite pulse transformers. The small-signal transformers provide greater than 1200 V isolation.

Features
• 1200 V or greater low-to-high side isolation.
• Drives Power Systems Operating on up to 575 V AC mains
• dv/dt immunity of greater than ±50V/ns
• Proprietary low-to-high side level translation and communication
• On-chip negative gate-drive supply to ensure Power MOSFET or IGBT turn-off and to prevent gate noise interference
• 5 V logic compatible HCMOS inputs with hysteresis
• Available in either the 16-Pin DIP or the 16-Pin wide-body, small-outline plastic package
• 20 ns switching time with 1000 pF load; 100 ns switching time with 10,000 pF load
• 100 ns propagation delay time
• 2 A peak output drive capability
• Self shut-down of output in response to over-current or short-circuit
• Under-voltage and over-voltage VDD lockout protection
• Protection from cross conduction of the half bridge
• Logic compatible fault indication from both low and high-side driver

Applications
• 1- or 3-Phase Motor Controls
• Switch Mode Power Supplies (SMPS)
• Uninterruptible Power Supplies (UPS)
• Induction Heating and Welding Systems
• Switching Amplifiers
• General Power Conversion Circuits
