Overview
The PAC5532QX is a Power Application Controller (PAC) system-on-chip optimized for high-speed BLDC motor control in 48V to 120V battery-powered applications. It integrates a 150MHz Arm Cortex-M4F microcontroller with 128kB flash and 32kB SRAM. The device features 29 I/Os, operates from -40°C to 125°C TA, and uses a 51-VFQFN exposed pad surface-mount package. It supports voltages up to 600V and includes programmable over-current protection.
Feature Summary
- Integrates a high-performance 32-bit ARM Cortex-M4F microcontroller core
- Includes all necessary analog and power management peripherals for motor drive stages
- Features fully programmable over-current protection mechanisms
Applications
- High-speed brushless DC motor control systems
- Battery-powered equipment operating at 48V to 120V
- Applications requiring integrated power management and MCU functionality
Procurement Notes
Verify the specific suffix 'QX' against official Qorvo documentation to confirm exact pinout, temperature grade, and packaging specifications. Ensure compatibility with existing board layouts regarding the 51-VFQFN exposed pad thermal requirements. Cross-reference the datasheet revision date to validate current manufacturing status and recommended design practices.
Selection Notes
Select this component when a combined MCU and motor driver solution is required for high-speed BLDC applications. The integrated architecture reduces external component count compared to discrete solutions. Consider the 150MHz processing speed and available memory resources for complex control algorithms. Verify that the 48V-120V input range aligns with the target system's power supply constraints.
Part Context
The PAC5532QX belongs to Qorvo’s Power Application Controller family, designed to simplify motor control designs. It consolidates digital control, analog sensing, and power switching drivers into a single silicon die. This integration targets cost-sensitive and space-constrained applications where reliability and performance are critical for electric drives.
Replacement Considerations
Consult Qorvo official substitution lists for direct replacements. Generic MCU or driver chips require significant redesign due to the PAC5532QX's integrated analog and power stage architecture.
