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 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 The device is a single input gate driver with Driver current capability: programmable deadtime, and also features an 2 A source typ. at 25 C active-low shutdown pin. 2.5 A sink typ. at 25 C Both device outputs can sink 2.5 A and source 2 Short propagation delay: 85 ns A, making the L6494 particularly suited for Switching times 25 ns rise/fall with 1 nF load medium and high capacity power Integrated bootstrap diode MOSFETs IGBTs. Single input and shutdown pin The independent UVLO protection circuits present on both the lower and upper driving Adjustable deadtime sections prevent the power switches from being 3.3 V, 5 V TTL/CMOS inputs with hysteresis 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 application PCB design simpler and more Flexible, easy and fast design compact, and help reducing the overall bill of material.
