LM5114

Single 7.6A Peak Current Low-Side Gate Driver

General Description

Features

●

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 capabil-

ity, the LM5114 can drive multiple FETs in parallel. The

LM5114 also has the features necessary to drive low-side en-

hancement 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. The inputs of the LM5114 are TTL/CMOS Logic

compatible and withstand the input voltages up to 14V re-

gardless of the VDD voltage. The LM5114 has split gate

outputs, providing flexibility to adjust the turn-on and turn-off

strength independently. The LM5114 has fast switching

speed and minimized propagation delays, facilitating high-

frequency operation. The LM5114 is available in SOT-23 6-

pin package and LLP-6 package with an exposed pad to aid

thermal dissipation.
