LM5114BMFX/S7003094
具有 4V UVLO 和分离输出的 7.6A/1.3A 单通道栅极驱动器 6-SOT-23 -40 to 125
General Description
The LM5114 is designed to drive low-side MOSFETs in boost type configurations or to drive secondary synchronous MOS FETs 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 non-inverting inputs to satisfy require ments for inverting and non-inverting gate drive in a single device type.
