PAC55713SR

Overview

The Qorvo PAC55713SR is a Power Application Controller optimized for high-speed BLDC motor control. It integrates a 150MHz Arm Cortex-M4F microcontroller, a multi-mode power manager, and configurable analog front-end peripherals within a TQFN-64 package. The device operates on a supply voltage range of 5.2 V to 70 V with a quiescent current of 300 uA. It features three high-side and three low-side gate drivers capable of delivering 1.2 A source and 1.8 A sink currents. Internal memory includes 128 kB flash and 32 kB SRAM, supporting industrial and automotive sensorless applications.

Feature Summary

• Integrated 150MHz Arm Cortex-M4F MCU with 128 kB Flash and 32 kB SRAM
• Three high-side (70V) and three low-side (20V) gate drivers with 1.2A/1.8A drive capability
• Configurable Analog Front-End featuring differential PGAs (x1-x48) and programmable overcurrent shutdown
• Built-in safety protections including VDS detection and cycle-by-cycle current limiting

Applications

• Industrial BLDC motor control for pumps and fans
• Robotics actuation systems
• Power tools and garden equipment
• Small home appliances

Procurement Notes

Verify the specific suffix 'SR' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications and moisture sensitivity levels. Ensure compatibility with the PAC5xxxEVK1 development kit for initial hardware validation. Confirm RoHS compliance status through the latest component documentation prior to procurement.

Selection Notes

Select the PAC55713SR when a 70V input rail and integrated high-current gate drivers are required for BLDC applications. The device is suitable for designs needing an embedded 150MHz MCU with advanced analog signal conditioning. Compare against the PAC55712 if pinout or specific peripheral configurations differ for the target PCB layout.

Part Context

The PAC55713SR belongs to the PAC55712/13 series of Power Application Controllers from Qorvo. This family combines Active-Semi’s power management technology with Qorvo’s analog front-end capabilities. The series targets compact motor drive solutions by integrating power processing, control logic, and protection circuits into a single system-on-chip architecture.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate the PAC55712-T as a potential alternative only if functional differences between the PAC55712 and PAC55713 variants are verified in the official datasheet.
