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
