Alpha and Omega Semiconductor Launches 3-Phase Driver IC, Increasing Battery Life of Cordless Power Tools and E-Mobility

AOZ32063MQV features high-side 100 percent duty cycle operation with integrated bootstrap diode, adjustable deadtime, and multiple protections for 3-phase BLDC motor drive designs

SUNNYVALE, Calif., Feb. 20, 2024Alpha and Omega Semiconductor Limited (AOS) (Nasdaq: AOSL), a designer, developer, and global supplier of a broad range of discrete power devices, wide band gap power devices, power management ICs, and modules, today announced the release of the AOZ32063MQV gate driver for BLDC motor applications. Available in a compact, 4mm x 4mm QFN-28L package, the highly integrated AOZ32063MQV is a 3-phase driver IC that offers superior driving ability, programmable deadtime, and sleep mode support. These capabilities deliver high motor operation efficiency and low standby power consumption that can help greatly increase the battery life of cordless power tools and e-mobility applications. The AOZ32063MQV is also an optimal driver IC solution for 3-phase Brushless DC (BLDC) motor drives. 

The new AOZ32063MQV 3-phase driver IC features multiple advanced protection functions, including input under-voltage protection, short-circuit protection, over-current protection, and thermal shutdown. With a wide input voltage range from 5V to 60V and supporting 0.8A source and 1A sink driving capability, the AOZ32063MQV also has a wide operating (-40°C to +125°C) ambient temperature range and offers high-side 100 percent duty cycle operation support. 

“Providing an economical and smaller-size PCB solution, the AOZ32063MQV, 3-phase driver IC, supports 100 percent duty operation and multiple protections in a compact 4 x 4 QFN package to satisfy customer < 60Vin BLDC motor control board design requirements. The AOZ32063MQV is capable of supporting the operation of two parallel MOSFETs delivering fast switching, efficiency, and advanced protection advantages that help to simplify and reduce BOM costs in today’s wide range of higher power BLDC motor application designs,” said Armin Hsu, Sr. Marketing Manager for motor driver products at AOS.
