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 (Ga N) FETs. The device consists of two 100V Ga N FETs driven by one high-frequency 90V Ga N FET driver in a half-bridge configuration.
Ga N FETs provide significant advantages for power conversion as they have zero reverse recovery and very small input capacitance CISS and output capacitance COSS. All the devices are mounted on a pletely 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 patible 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 Ga N FETs are within a safe operating...
