PAC5532B

160 V BLDC Controller and Driver with Power Manager and Configurable AFE

Qorvo's PAC5532B 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 PAC5532B integrates a 150 MHz Arm Cortex-M4F with 128 kB FLASH, power management, 2 A gate drivers and signal conditioning in a small single product.

PAC5532B is optimized for high-power 40 V-100 V battery-powered BLDC motor control applications.
