LM51061.2-A, 1.8-A 100-V half bridge gate driver with 8V-UVLO and programmable dead-time | Power Management (PMIC) | 6 | Active | The LM5106 is a high voltage gate driver designed to drive both the high side and low side N-Channel MOSFETs in a synchronous buck or half bridge configuration. The floating high side driver is capable of working with rail voltages up to 100V. The single control input is compatible with TTL signal levels and a single external resistor programs the switching transition dead-time through tightly matched turn-on delay circuits. The robust level shift technology operates at high speed while consuming low power and provides clean output transitions. Under-voltage lockout disables the gate driver when either the low side or the bootstrapped high side supply voltage is below the operating threshold. The LM5106 is offered in the VSSOP-10 or thermally enhanced 10-pin WSON plastic package.

LM51131.2-A/5-A, 90-V half bridge gate driver for GaNFET | Development Boards, Kits, Programmers | 5 | Active | The LM5113 device 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 100 V. The high-side bias voltage is generated using a bootstrap technique and is internally clamped at 5.2 V, 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 14 V regardless of the VDD voltage. The LM5113 has split gate outputs, providing flexibility to adjust the turnon and turnoff strength independently.
The LMG1205 is an enhancement over the LM5113. The LMG1205 takes the design of the LM5113 and includes start-up logic, level shifter, and power-off Vgs clamp enhancements to provide a more robust solution.

The LM5113 is available in a standard WSON-10 pin package and a 12-bump DSBGA package. The WSON-10 pin package contains an exposed pad to aid power dissipation. The DSBGA package offers a compact footprint and minimized package inductance.
