DESCRIPTION  
The LM5113 is designed to drive both the high-side and the low-side enhancement mode Gallium Nitride (GaN)  
FETs in a synchronous buck or a half bridge configuration. The floating high-side driver is capable of driving a  
high-side enhancement mode GaN FET operating up to 100V. The high-side bias voltage is generated using a  
bootstrap technique and is internally clamped at 5.2V, which prevents the gate voltage from exceeding the  
maximum gate-source voltage rating of enhancement mode GaN FETs. The inputs of the LM5113 are TTL logic  
compatible, and can withstand input voltages up to 14V regardless of the VDD voltage. The LM5113 has split  
gate outputs, providing flexibility to adjust the turn-on and turn-off strength independently.  
In addition, the strong sink capability of the LM5113 maintains the gate in the low state, preventing unintended  
turn-on during switching. The LM5113 can operate up to several MHz. The LM5113 is available in a standard  
LLP-10 pin package and a 12-bump micro SMD package. The LLP-10 pin package contains an exposed pad to  
aid power dissipation. The micro SMD package offers a compact footprint and minimized package inductance.  
Packages  
LLP-10 (4 mm x 4 mm)  
micro SMD (2 mm x 2 mm)
