PAC5556AQX-T

Application Specific Microcontrollers Overview

The PAC5556AQX-T is a high-voltage Brushless DC (BLDC) motor controller and driver manufactured by Qorvo. It integrates a Cortex-M4F MCU, power management, half-bridge gate drivers, and an analog front end on a single System-on-Chip (SoC). The device supports supply voltages up to 600 V and delivers an output current of 1 A. It operates within a temperature range of -40 °C to +125 °C and utilizes a surface-mount package. The integrated architecture enables efficient control for BLDC and PMSM motors in demanding industrial applications.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'T' against official Qorvo documentation to confirm tape-and-reel packaging requirements. Ensure compatibility with the PAC5556 family pinout and thermal specifications during integration. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly.

Application Specific Microcontrollers Selection Notes

Select this component for designs requiring a unified solution for high-voltage motor control without external discrete drivers. The integrated MCU reduces bill-of-materials complexity compared to separate controller and driver ICs. Verify that the 1 A output current meets the gate charge requirements of the selected external SiC or GaN FETs.
