General Description
The IXA611 is a 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 IXA611 can
withstand dV/dt on the output side up to ± 50V/ns.
The IXA611 comes in either the 16-PIN SOIC package
(IXA611S3) or the 14-PIN DIP through-hole package
(IXA611P7)

600mA 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 IXA611 is ESD sensitive.
