Product overview

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.

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.

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.

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.
