Qorvo PAC5285 Power Applications Controller®

Qorvo PAC5285 Power Applications Controller® is a highly-integrated low-power BLDC controller and driver that combines a Flash-programmable MCU, power management, signal conditioning, and a 3-phase BLDC inverter into a single product. The PAC5285 features a 50MHz Arm® Cortex®-M0 core with 32kB of Flash and 8KB of SRAM. The device also has access to several different analog and digital peripherals used for BLDC motor control and driving.

The high level of integration and single-chip design of the PAC5285 significantly reduces PCB size and BOM, making it ideal for extremely compact, low-power, 2S to 6S battery-powered BLDC intelligent motor control. This device consumes a very low hibernate current of 8µA @ 12VDC.

The PAC5285 includes a single 40V power supply input, ideal for 12V battery-powered applications. The DC-DC charge pump converts the power supply input into an IC and inverter power supply, and regulators for a 5V system supply core, and analog supplies.

The PAC5285 also integrates a differential amplifier for sensing motor current for over-current protection and motor control. The inverter may be configured to shut down during over-current, over-voltage, under-voltage, and over-temperature events. The power monitor allows the ADC to sample all power supply rails internally. This device contains six 40V/300mΩ MOSFETs to support 3-phase BLDC motor applications.

The Qorvo PAC5285 Power Applications Controller is available in a 6.0mm x 6.0mm, 40-lead QFN package.
