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)
