DESCRIPTION
The logic inputs are CMOS/TTL compatible down to 3.3 V for easy interfacing microcontroller or DSP. The device is a single input gate driver with programmable deadtime, and also features an active-low shutdown pin. 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.
