Alpha and Omega launches 3-phase driver chip


Increases battery life of cordless power tools and e-mobility

Power chip company Alpha and Omega Semiconductor has released the AOZ32063MQV gate driver for BLDC motor applications.

Available in a 4mm x 4mm QFN-28L package, the highly integrated AOZ32063MQV is a 3-phase driver IC that is said to offer superior driving ability, programmable deadtime, and sleep mode support.

These capabilities deliver high motor operation efficiency and low standby power consumption that can help increase the battery life of cordless power tools and e-mobility applications. The AOZ32063MQV is suitable for use with 3-phase Brushless DC (BLDC) motor drives.

The new AOZ32063MQV 3-phase driver IC features 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, senior. marketing manager for motor driver products at AOS.

The AOZ32063MQV is immediately available in production quantities with a lead time of 24 weeks. The unit price in 1,000-piece quantities is $1.55 .
