IX6Q11
1 MHz, 300 Volt, 6 Ampere High & Low-side Driver for N-Channel MOSFETs and IGBTs
Features
* Floating High Side Driver with boot-strap Power supply along with a Low Side Driver. * Fully operational to 300V* * 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: 6A * Matched propagation delay for both outputs * Low output impedance * Low power supply current * Immune to negative voltage transients
General Description
The IX6Q11 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 bus voltage up to 300V in dynamic conditions. 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 IX6Q11 can withstand dV/dt on the output side up to 50V/ns.
Ordering Information
The IX6Q11 is available in the 14-Pin DIP, the 16-Pin SOIC, and the heat-sinkable 18-Pin SOIC CooltabTM packages.
