| IX4R11 4A Half-Bridge Driver 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 Preliminary Data Sheet 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. The IX4R11 comes in either the 16-PIN SOIC package (IX4R11S3) or the 14-PIN DIP through-hole package (IX4R11P7) 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 Warning: The IX4R11 is ESD sensitive.
