Texas Instruments LMG2100R026 GaN Half-Bridge Power Stage
Texas Instruments LMG2100R026 GaN Half-Bridge Power Stage integrates gate-driver and enhancement-mode Gallium Nitride (GaN) FETs. The 93V continuous, 100V pulsed, 53A half-bridge power stage includes two GaN FETs driven by one high-frequency GaN FET driver in a half-bridge configuration. The driver and the two GaN FETs are mounted on a fully bond-wire-free package platform with minimized package parasitic elements.
The TI LMG2100R026 Power Stage is housed in a 7.0mm x 4.5mm x 0.89mm lead-free package that 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 guarantees the gate voltages of the enhancement mode GaN FETs are within a safe operating range. The device extends the benefits of discrete GaN FETs by allowing a more user-friendly interface. The device is an ideal solution for applications requiring high-frequency, high-efficiency operation in a small form factor.
