SNVS790F – JANUARY 2012 – REVISED NOVEMBER 2015 LM5114 Single 7.6-A Peak Current Low-Side Gate Driver
1 Features 3 Description 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 highfrequency operation. The LM5114 is available in a 6pin SOT-23 package and a 6-pin WSON package …
