Key challenges in improving power efficiency
in low-power, battery-powered motor
applications include minimizing copper and
core losses while maintaining high power
density. Failing to address these can result
in poor thermal management, leading to
heating issues and the inability to meet
desired operating points."
Qorvo helps designers develop the most power-
efficient motor control systems by
• Providing advanced modulation techniques, such
as five-state PWM, to minimize switching losses
and enhance system efficiency
• Providing single-shunt current sensing solutions to
reduce cost and power loss
• Incorporating low-power sleep modes and
hibernation features to significantly reduce
standby energy consumption
• Driving power switches optimally with integrated
configurable smart gate drivers
• Simplifying the design of high-efficiency auxiliary
power supplies with integrated multimode power
management building blocks
