3 Description

The LMG2100R044 device is an 80-V continuous,

100-V pulsed, 35-A half-bridge power stage,

with integrated gate-driver and enhancement-mode

Gallium Nitride (GaN) FETs. The device consists of

two 100-V GaN FETs driven by one high-frequency

80-V GaN FET driver in a half-bridge configuration.

GaN FETs provide significant advantages for power

conversion as they have near zero reverse recovery

and very small input capacitance CISS and output

capacitance COSS. 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 5.5 mm × 4.5

mm × 0.89 mm lead-free package and can be easily

mounted on PCBs.

The TTL logic compatible inputs can withstand input

voltages up to 12 V 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 highfrequency,

high-efficiency operation in a small form

factor.
