General Description
The IX4R11 Bridge Driver for N-channel MOSFETs and IGBTs with a high side and low side output, whose input signals reference the low side. The High Side driver can control a MOSFET or IGBT connected to a positive buss voltage up to 650V. The logic input stages are compatible with TTL or CMOS, have built-in hysteresis and are fully immune to latch up over the entire operating range. The IX4R11 can withstand dV/dt on the output side up to ± 50V/ns.

Features
• Floating High Side Driver with boot-strap Power supply along with a Low Side Driver.
• Fully operational to 650V
• ± 50V/ns dV/dt immunity
• Gate drive power supply range: 10 - 35V
• Undervoltage lockout for both output drivers
• Separate Logic power supply range: 3.3V to VCL
• Built using the advantages and compatibility of CMOS and IXYS HDMOSTM processes
• Latch-Up protected over entire operating range
• High peak output current: 4A
• Matched propagation delay for both outputs
• Low output impedance
• Low power supply current
• Immune to negative voltage transients

Applications
• Driving MOSFETs and IGBTs in half-bridge circuits
• High voltage, high side and low side drivers
• Motor Controls
• Switch Mode Power Supplies (SMPS)
• DC to DC Converters
• Class D Switching Amplifiers
