L6498 High voltage high and low-side 2 A gate driver Datasheet - production data Description The L6498 is a high voltage device manufactured SO-8 SO-14 with the BCD6 OFF-LINE technology. It is a single chip half-bridge gate driver for the N-channel power MOSFET or IGBT. The high-side (floating) section is designed to stand a DC voltage rail up to 500 V, with 600 V Features transient withstand voltage. The logic inputs are Transient withstand voltage 600 V CMOS/TTL compatible down to 3.3 V for easy interfacing control units such as microcontrollers dV/dt immunity 50 V/ns in full temperature or DSP. range Both device outputs can sink 2.5 A and source 2 Driver current capability: A, making the L6498 particularly suited for 2 A source typ. at 25 C medium and high capacity power 2.5 A sink typ. at 25 C MOSFETs IGBTs. Short propagation delay: 85 ns The outputs cannot be simultaneously driven high Switching times 25 ns rise/fall with 1 nF load thanks to an integrated interlocking function. 3.3 V, 5 V TTL/CMOS inputs with hysteresis The independent UVLO protection circuits Integrated bootstrap diode present on both the lower and upper driving sections prevent the power switches from being Interlocking function operated in low efficiency or dangerous UVLO on both high-side and low-side sections conditions. Compact and simplified layout The integrated bootstrap diode as well as all of Bill of material reduction the integrated features of this driver make the Flexible, easy and fast design application PCB design simpler and more compact, and help to reduce the overall bill of material.
