5 GaN IPM DRV7308 for High-Efficiency Fan Drive

The DRV7308 integrates six high-performance Gallium Nitride (GaN) Intelligent Power Modules (IPMs), achieving an efficiency of over 99%. Compared to traditional IGBTs and MOSFETs, it reduces power loss by 50%. This performance advantage not only significantly enhances the energy efficiency of motor drive systems but also drastically minimizes energy loss. The chip's unique 12mm x 12mm package design makes the DRV7308 an industry-leading ultra-compact, high-efficiency IPM for motor drive applications ranging from 150W to 250W. Due to its high efficiency, the DRV7308 eliminates the need for external heat sinks. Compared to similar IPM solutions, the size of the motor drive inverter printed circuit board (PCB) can be reduced by 55%, assisting engineers in developing more efficient and compact air-conditioning fan drives.

The TIDA-010273 is a 250W motor inverter reference design, which shows the capabilities of DRV7308.
