L6494 High voltage high and low-side 2 A gate driver Datasheet - production data Description The L6494 is a high-voltage device manufactured with the BCD6 “offline” technology. It is a single chip half-bridge gate driver for N-channel power MOSFETs or IGBTs. SO-14 Features  Transient withstand voltage 600 V  dV/dt immunity ± 50 V/ns in full temperature range The high-side (floating) section is designed to stand a DC voltage rail up to 500 V, with 600 V transient withstand voltage. The logic inputs are CMOS/TTL compatible down to 3.3 V for easy interfacing control units such as microcontrollers or DSP.  Driver current capability: – 2 A source typ. at 25 °C – 2.5 A sink typ. at 25 °C The device is a single input gate driver with programmable deadtime, and also features an active-low shutdown pin.  Short propagation delay: 85 ns Both device outputs can sink 2.5 A and source 2 A, making the L6494 particularly suited for medium and high capacity power MOSFETs\IGBTs.  Switching times 25 ns rise/fall with 1 nF load  Integrated bootstrap diode  Single input and shutdown pin  Adjustable deadtime  3.3 V, 5 V TTL/CMOS inputs with hysteresis  UVLO on both high-side and low-side sections  Compact and simplified layout The independent UVLO protection circuits present on both the lower and upper driving sections prevent the power switches from being operated in low efficiency or dangerous conditions. The integrated bootstrap diode as well as all of the integrated features of this driver make the application PCB design simpler and more compact, and help reducing the overall bill of material.  Bill of material reduction  Flexible, easy and fast design Applications  Motor driver for home appliances, factory automation, industrial drives and fans  HID ballasts  Induction heating  Welding  Industrial inverters  UPS  Power supply units  DC-DC converters November 2017 This is information on a product in full production.
