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 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 5.5mm ×

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 highfrequency,

high-efficiency operation in a small form

factor.
