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)

4A Half-Bridge Driver
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.
