    Qorvo's PAC5285 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 PAC5285 integrates a 50MHz Arm Cortex-M0 with 32kB FLASH, power management, gate drivers and power MOSFETs and signal conditioning in a small single product.

    PAC5285 is optimized for low-power BLDC motor control applications up to 20W.
