PAC5285

40 V, 20 W Intelligent BLDC Motor Control Module with Integrated FETs

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 50 MHz Arm Cortex-M0 with 32 kB 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 20 W.
