PAC55724-T

Overview

The Qorvo PAC55724-T 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 configurable analog front end and dedicated power drivers. The device supports input voltages up to 72V and includes features such as Vds detection, cycle-by-cycle current limiting, and simultaneous sampling and hold capabilities. This system-on-chip solution combines processing power with integrated gate drivers to simplify the design of compact motor drive systems.

Feature Summary

• Integrates a 150MHz Arm Cortex-M4F 32-bit MCU with 128kB Flash and 32kB SRAM
• Supports 72V input voltage with integrated buck/SEPIC DC/DC controller
• Features three high-side and three low-side gate drivers with 1.2A source and 1.8A sink currents
• Includes configurable analog front end with programmable gain amplifiers and simultaneous sampling

Applications

• Industrial BLDC motor control for pumps and fans
• Robotics and warehouse automation systems
• Electric mobility devices such as scooters and wheelchairs
• Power tools and garden equipment

Procurement Notes

Verify the specific suffix and tape-and-reel quantity requirements directly with the manufacturer or authorized distributors. Confirm lead times and availability status prior to ordering, as supply chain conditions may vary. Ensure that the selected package variant matches the intended PCB footprint and thermal management strategy.

Selection Notes

Select the PAC55724-T when a combined MCU and gate driver solution is required for 72V BLDC applications. Consider the integrated power management features if board space is limited. Verify that the internal flash and RAM capacities meet the firmware complexity requirements. Compare against other PAC55xx series variants if different voltage ratings or driver configurations are needed.

Part Context

The PAC55724 belongs to Qorvo's Power Application Controller family, which merges microcontroller functionality with power stage integration. This approach reduces component count and board size compared to discrete solutions. The PAC55724 specifically targets applications requiring robust motor control with integrated protection features like overcurrent and Vds monitoring.

Replacement Considerations

Check for pin-compatible alternatives within the PAC55xx series, such as the PAC55712 or PAC55713, if different driver specifications or package options are preferred. Verify functional equivalence regarding voltage ratings and memory sizes before substituting.
