TI LMG3425R030RQZT

The LMG342xR030 GaN FET features an integrated driver and protection functions, enabling designers to achieve a higher level of power density and efficiency in power electronics systems. The LMG342xR030 integrates a silicon driver, capable of achieving a switching speed of up to 150V/ns. Compared with discrete silicon gate drivers, TI's integrated precision gate bias enables a higher switching SOA. This integration feature, combined with TI's low-inductance packaging technology, provides clean switching and ultra-low ringing in hard-switching power supply topologies. The adjustable gate drive strength allows the slew rate to be controlled between 20 V/ns and 150 V/ns, which can be used to actively control EMI and optimize switching performance. The LMG3425R030 includes an ideal diode mode, which reduces third-quadrant losses by enabling the adaptive dead-time control function. Advanced power management functions include digital temperature reporting and fault detection. The temperature of the GaN FET is reported through a variable-duty-cycle PWM output, which simplifies device load management. Reported faults include over-temperature, over-current, and UVLO monitoring.
