Texas Instruments  LM5113QDPRRQ1

The LM5113-Q1 is designed to drive both the high-side and the low-side enhancement modeGallium Nitride (GaN) FETs or silicon MOSFETs in a synchronous buck, boost, or half bridgeconfiguration for automotive applications. The device has an integrated 100-V bootstrap diode andindependent inputs for the high-side and low-side outputs for maximum control flexibility. Thehigh-side bias voltage is internally clamped at 5.2 V, which prevents the gate voltage fromexceeding the maximum gate-source voltage rating of enhancement mode GaN FETs. The inputs of thedevice are TTL-logic compatible, which can withstand input voltages up to 14 V regardless of theVDD voltage. The LM5113-Q1 has split-gate outputs, providing flexibility to adjust the turnon andturnoff strength independently.

In addition, the strong sink capability of the LM5113-Q1 maintains the gate in the lowstate, preventing unintended turnon during switching. The LM5113-Q1 can operate up to several MHz.The LM5113-Q1 is available in a standard 10-pin WSON package with an exposed pad to aid powerdissipation.
