3 Description
The LMG2652 is a 650V 140mΩ GaN power-FET
half bridge. The LMG2652 simplifies design, reduces
component count, and reduces board space by
integrating half-bridge power FETs, gate drivers,
bootstrap diode, and high-side gate-drive level shifter
in a 6mm by 8mm QFN package.
The low-side current-sense emulation reduces power
dissipation compared to the traditional current-sense
resistor and allows the low-side thermal pad to be
connected to the cooling PCB power ground.
The high-side GaN power FET can be controlled with
either the low-side referenced gate-drive pin (INH)
or the high-side referenced gate-drive pin (GDH).
The high-side gate-drive signal level shifter reliably
transmits the INH pin signal to the high-side gate
driver in challenging power switching environments.
The smart-switched GaN bootstrap FET has no diode
forward-voltage drop, avoids overcharging the highside
supply, and has zero reverse-recovery charge.
The LMG2652 supports converter light-load efficiency
requirements and burst-mode operation with low
quiescent currents and fast start-up times. Protection
features include FET turn-on interlock, under-voltage
lockout (UVLO), cycle-by-cycle current limit, and overtemperature
shut down.
