The LM5111 Dual Gate Driver replaces industry standard gate drivers with improved peak output current and efficiency. Each compound output driver stage includes MOS and bipolar transistors operating in parallel that together sink more than 5-A peak from capacitive loads. Combining the unique characteristics of MOS and bipolar devices reduces drive current variation with voltage and temperature. Undervoltage lockout protection is also provided. The drivers can be operated in parallel with inputs and outputs connected to double the drive current capability. This device is available in the SOIC package or the thermally enhanced
MSOP-PowerPAD package.
