Qorvo – 48V Charge Pump BLDC Motor Driver with Programmable Current – PAC5526

Qorvo’s PAC5526 belongs to Qorvo’s Power Application Controller (PAC) family. This family features highly-optimized SOC devices that can implement BLDC or PMSM programmable motor controller and driver functionality in a single integrated IC.

The product integrates a high-performance, high-memory FLASH-based 150MHz Arm® Cortex-M4F®, power management, high-side and low-side gate drivers and signal conditioning components in a single product.

PAC5526 is optimized for high-performance battery-powered BLDC motor control applications up to 24V.

Key Features

  • Fully programmable 150 MHz Arm® Cortex-M4F®
  • 128K FLASH, 32kB SRAM, 12-bit, 2.5MSPS ADC with sequencer
  • Integrated 48V input charge pump DC/DC and buck-boost DC/DC
  • Programmable-current gate drivers (60mA to 1A)
  • Integrated PGA, DACs and comparators
  • UART, CAN, I2C & SPI serial interfaces
  • 6x6mm, 48-pin QFN package
  • Ideal for power tools
