PAC55724SR

Overview

The Qorvo PAC55724SR is a Power Application Controller (PAC) designed for high-performance Brushless DC (BLDC) motor control applications. It integrates a 150MHz Arm Cortex-M4F microcontroller with a proprietary Multi-Mode Power Manager and Configurable Analog Front End. The device supports input voltages from 5.2V to 70V, featuring three high-side and three low-side gate drivers capable of handling up to 1.2A source and 1.8A sink currents. It includes a 2.5MSPS ADC with programmable auto-sampling, VDS detection, and advanced protection mechanisms such as cycle-by-cycle current limiting. Packaged in a TQFN-64 format, it targets industrial automation, power tools, and electric mobility systems.

Part Context

The PAC55724SR belongs to the Qorvo PAC557xx series of intelligent motor controllers. This family combines analog front-end capabilities with digital control cores to simplify BLDC and PMSM motor drive designs. The device is part of a broader ecosystem that includes evaluation kits like the PAC55724EVK1 for development and validation purposes.

Replacement Considerations

The PAC55713SR is a closely related component within the same PAC5571x/2x family, sharing similar architectural features and pinout compatibility considerations. Designers should verify specific peripheral configurations and firmware compatibility when substituting between these variants.
