The LM5114 is 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. The LM5114 also has the features necessary to drive low-side enhancement mode Gallium Nitride (GaN) FETs. The LM5114 provides inverting and noninverting inputs to satisfy requirements for inverting and Noninverting gate drive in a single device type. The inputs of the LM5114 are TTL/CMOS Logic compatible and withstand input voltages up to 14 V regardless of the VDD voltage. The LM5114 has split gate outputs, providing flexibility to adjust the turnon and turnoff strength independently. The LM5114 has fast switching speed and minimized propagation delays, facilitating high-frequency operation. The LM5114 is available in a 6-pin SOT-23 package and a 6-pin WSON package with an exposed pad to aid thermal dissipation.
