Preliminary Data Sheet
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)
