The LM5114BMF/NOPB is a single 7.6A peak current low-side Gate Driver designed to drive low-side MOSFETs in boost type configurations or to drive secondary synchronous MOSFETs in isolated topologies. With strong sink current capability, the LM5114 can drive multiple FETs in parallel and also has the features necessary to drive low-side enhancement mode Gallium Nitride (GaN) FETs. The driver provides inverting and non-inverting inputs to satisfy requirements for inverting and non-inverting gate drive in a single device type. The inputs of the driver are TTL/CMOS Logic compatible and withstand the input voltages up to 14V regardless of the VDD voltage. The Driver has split gate outputs, providing flexibility to adjust the turn-on and turn-off strength independently. This gate driver has fast switching speed and minimized propagation delays, facilitating high-frequency operation.
