PAC55712SR

Overview

The Qorvo PAC55712SR is a Power Application Controller (PAC) optimized for high-speed BLDC motor control. It integrates a 150MHz Arm Cortex-M4F microcontroller, a 70V SEPIC DC/DC controller with external N-channel FETs, and dedicated power drivers. The device operates within a supply voltage range of 5.2 V to 70 V and delivers an output current of 1.2 A. Quiescent current is specified at 300 uA. It features three high-side and three low-side gate drivers in a TQFN-64 package.

Feature Summary

Integrates a 150MHz Arm Cortex-M4F MCU with 128kB Flash and 32kB SRAM
Includes a 70V SEPIC DC/DC controller requiring external N-channel FETs
Features three high-side (70V, 1.2A source/1.8A sink) and three low-side (20V, 1.2A source/1.8A sink) gate drivers
Contains configurable analog front-end with differential and single-ended PGAs

Applications

Industrial BLDC motor control for pumps and fans
Robotics applications
Power tools and garden equipment
Small home appliances
E-mobility systems

Part Context

The PAC55712SR belongs to the PAC5571x series, which shares identical electrical specifications and pinout compatibility with the PAC55713 model. Both variants are designed as system-level solutions for smart appliances and industrial systems, differing primarily in internal configuration or firmware support rather than hardware parameters.

Replacement Considerations

The PAC55713SR is a direct functional equivalent within the same series, sharing identical electrical characteristics and packaging. Designers may substitute between these part numbers based on specific firmware requirements or availability without altering the hardware design.
