DRV7308 GaN Intelligent Power Module (IPM)
Candidate for:2024 World Electronics Achievement Awards - Power Semiconductor/Driver
The DRV7308 is the industry’s first 650V, three-phase GaN IPM for 250W motor drive applications used in major home appliances and heating, ventilation and air-conditioning (HVAC) systems. The GaN IPM enables high efficiency, as well as optimized acoustic performance, reduced solution size and lower system costs. The DRV7308 helps engineers meet stringent efficiency standards such as SEER, MEPS, Energy Star and Top Runner for appliances and HVAC systems -- leveraging GaN technology to deliver more than 99% efficiency and improve thermal performance, with 50% reduced power losses compared to existing solutions. In addition, the DRV7308 achieves industry-low dead time and low propagation delay, both less than 200ns, enabling higher pulse-width modulation (PWM) switching frequencies that reduce audible noise and system vibration. These advantages plus the higher power efficiency and integrated features of the DRV7308 also reduce motor heating, which can improve reliability and extend the lifetime of the system.
Supporting the trend of more compact home appliances, the DRV7308 helps engineers develop smaller motor drive systems. Enabled by GaN technology, the new IPM delivers high power density in a 12mm-by-12mm package, making it the industry’s smallest IPM for 250W motor-drive applications. Because of its high efficiency, the DRV7308 eliminates the need for an external heatsink, resulting in motor drive inverter printed circuit board (PCB) size reduction of up to 55% compared to competing IPM solutions. The integration of a current sense amplifier, protection features and inverter stage further reduces solution size and cost.
