Description
The LM5113-Q1 is designed to drive both the highside and the low-side enhancement mode Gallium Nitride (GaN) FETs or silicon MOSFETs in a synchronous buck, boost, or half bridge configuration for automotive applications. The device has an integrated 100-V bootstrap diode and independent inputs for the high-side and low-side outputs for maximum control flexibility. The high-side bias voltage is internally clamped at 5.2 V, which prevents the gate voltage from exceeding the maximum gatesource voltage rating of enhancement mode GaN FETs. The inputs of the device are TTL-logic compatible, which can withstand input voltages up to 14 V regardless of the VDD voltage. The LM5113-Q1 has split-gate outputs, providing flexibility to adjust the turnon and turnoff strength independently.
