LM5113/LM5113-Q1 Half-Bridge Gate Driver

Texas Instruments LM5113/LM5113-Q1 Half-Bridge Gate Driver 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. This clamping prevents the gate voltage from exceeding the maximum gate-source voltage rating of enhancement mode GaN FETs. The inputs of the LM5113/LM5113-Q1 are TTL logic compatible and can withstand input voltages up to 14V regardless of the VDD voltage. The LM5113/LM5113-Q1 has split gate outputs, providing flexibility to adjust the turn-on and turn-off strength independently. The LM5113-Q1 devices are AEC-Q100 qualified for automotive applications.
