3 Description

The LMG2100R044 device is a 90V continuous, 100V pulsed, 35A half-bridge power stage, with integrated gate-driver and enhancement-mode Gallium Nitride (GaN) FETs. The device consists of two 100V GaN FETs driven by one high-frequency 90V GaN FET driver in a half-bridge configuration.

GaN FETs provide significant advantages for power conversion as they have zero reverse recovery and very small input capacitance C_ISS and output capacitance C_OSS. All the devices are mounted on a completely bond-wire free package platform with minimized package parasitic elements. The LMG2100R044 device is available in a 5.5mm × 4.5mm × 0.89mm lead-free package and can be easily mounted on PCBs.

The TTL logic compatible inputs can support 3.3V and 5V logic levels regardless of the VCC voltage. The proprietary bootstrap voltage clamping technique ensures the gate voltages of the enhancement mode GaN FETs are within a safe operating range.

The device extends advantages of discrete GaN FETs by offering a more user-friendly interface. It is an ideal solution for applications requiring high-frequency, high-efficiency operation in a small form factor.
