Description
The L6399 is a high voltage device manufactured
using BCD™ “offline” technology. It is a singlechip
half bridge gate driver for N-channel power
MOSFETs or IGBTs.
The high-side (floating) section is designed to
withstand a voltage rail up to 600 V. The logic
inputs are CMOS/TTL compatible down to 3.3 V
for easy microcontroller/DSP interfacing.

 Motor drivers DC, AC, PMDC and PMAC
motors systems
 HVAC
 Factory automation
 Power supply systems
 Compressors
 Fans
 Lighting applications
