PAC5523

72 V BLDC Controller and Driver with Integrated Multimode Power Manager and Configurable AFE

Qorvo's PAC5523 belongs to Qorvo's Power Application Controller (PAC) product family. This family features highly-optimized SOC devices that can implement BLDC or PMSM programmable motor controller and driver in a single integrated IC.

The PAC5523A integrates a 150 MHz Arm Cortex-M4F with 128 kB FLASH, power management, 1.5 A gate drivers and signal conditioning in a small single product.

PAC5523 is optimized for high-performance battery-powered BLDC motor control applications up to 48 V.
