IXA611S3

IXA611 Preliminary Data Sheet 600mA Half-Bridge Driver Features General Description • 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 • Built using the advantages and compatibility of CMOS and IXYS HDMOSTM processes • Latch-Up protected over entire operating range • High peak output current: 600 mA • Matched propagation delay for both outputs • Low output impedance • Low power supply current • Immune to negative voltage transients 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) Applications • • • • • • Warning: The IXA611 is ESD sensitive.
