            Smart Driver L639x Series 
                    STMicroelectronics introduces a highly versatile, innovative solution for MOSFET and IGBT drivers
    

Smart Driver L639x Series STMicroelectronics' L639x is a highly integrated, versatile high voltage gate driver platform, which allows the user to easily design a control system for a wide range of inductive loads such as motors for home appliances, factory automation, industrial drives and also HID ballasts and power supply units.

The L6390, L6392, and L6393 are high-voltage devices manufactured with the BCD "OFF-LINE" technology. They are single chip half-bridge gate drivers for 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 easy interfacing microcontroller/DSP.
