Description
The L6398 is a high
voltage device manufactured with the BCD™ “offline” technology. It is a singlechip half bridge gate driver for the N-channel power
MOSFET or IGBT.
The high-side (floating) section is designed to stand a
voltage rail up to 600 V. The logic inputs are
CMOS/TTL compatible down to 3.3 V for the easy interfacing microcontroller/DSP.
