The IX2R11 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 IX2R11 can withstand dV/dt on the output side up to ± 50V/ns.
The IX2R11 comes in either the 16-PIN SOIC package (IX2R11S3) or the 14-PIN DIP through-hole package (IX2R11P7)
