The LMG365xR025 GaN FET with integrated driver and protection is targeted at switch-mode power converters and enables designers to achieve new levels of power density and efficiency.

Adjustable gate driver strength allows the control of turn-on and maximum turn-off slew rates independently, which can be used to actively control EMI and optimize switching performance. Turn on slew rate can be varied from 10V/ns to 100V/ns, while the turn off slew rate can be limited from 10V/ns to a maximum based on the magnitude of load current. Protection features include under-voltage lockout (UVLO), cycle-by-cycle overcurrent limit, short-circuit and overtemperature protection. The LMG3651R025 provides a 5V LDO output on LDO5V pin that can be used to power external digital isolator. The LMG3656R025 includes the zero-voltage detection (ZVD) feature which provides a pulse output from the ZVD pin when zero-voltage switching is realized. The LMG3657R025 includes the zero-current detection (ZCD) feature that sets the ZCD pin high when the drain-to-source current is negative and transitions to low upon detecting the zero-crossing point.
