PAC5523QM

Application Specific Microcontrollers Overview

The Qorvo PAC5523QM is a Power Application Controller (PAC) designed for motor, motion, and ignition applications. It integrates an ARM Cortex-M4 microcontroller with 128kB of Flash memory into a single system-on-chip optimized for brushless DC (BLDC) motor control. The device features a half-bridge driver architecture capable of handling supply voltages up to 70V. Key electrical specifications include a maximum output current of 1.5A and a quiescent operating supply current of 300µA. It operates within a temperature range of -40°C to +125°C and utilizes a TQFN-48 surface-mount package.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'QM' against the manufacturer's official datasheet to confirm pinout compatibility and packaging details. Ensure that the TQFN-48 footprint matches the target PCB design. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly to prevent component damage during manufacturing.

Application Specific Microcontrollers Selection Notes

Select this component when a combined MCU and gate driver solution is required for 70V BLDC applications. The 128kB Flash capacity supports complex control algorithms without external memory. Compare the 1.5A drive strength against load requirements to ensure adequate margin. Verify that the TQFN-48 package size fits within the available board space constraints.

Application Specific Microcontrollers Part Context

The PAC5523QM belongs to the Qorvo PAC5523 series of Power Application Controllers. This family integrates microcontroller functionality with power management and motor driving capabilities. Other variants in the series may differ in memory size, voltage ratings, or package configurations, requiring careful cross-referencing of datasheets for specific model distinctions.

Application Specific Microcontrollers Replacement Considerations

Direct substitutes require matching the 70V rating, 1.5A drive current, and TQFN-48 package. Verify functional equivalence of the integrated Cortex-M4 core and Flash memory size. Check for compatible pinouts to avoid redesigning the host circuitry.
