Overview
The MP6523GR-Z is a triple half-bridge motor driver manufactured by Monolithic Power Systems. It features serial input control and is designed for brushless DC motor applications. The device operates within a supply voltage range of 7 V to 28 V. It supports an output current of 900 mA per channel with a maximum power dissipation of 3 W. The component functions across a temperature range from -40°C to +150°C TJ. It utilizes a QFN-24 package for surface mount installation.
Feature Summary
- Integrates three half-bridge drivers for controlling external MOSFETs in BLDC motor applications
- Utilizes serial interface for simplified control logic and reduced pin count
- Includes internal protection mechanisms such as overcurrent, overtemperature, and undervoltage lockout
Applications
- Brushless DC (BLDC) motor drive systems
- Industrial motion control circuits
- Automotive electronic modules requiring robust motor driving capabilities
Procurement Notes
Verify the specific suffix Z indicates RoHS compliance and halogen-free status against the manufacturer's latest documentation. Confirm the QFN-24 package dimensions match your PCB footprint requirements. Ensure the serial communication protocol aligns with your microcontroller interface specifications before finalizing procurement.
Selection Notes
Select this component when a compact solution for driving three-phase motors is required without integrated high-side switches. Consider the 900 mA output capability relative to your external MOSFET gate charge requirements. Evaluate the thermal performance of the QFN-24 package under your specific load conditions to ensure reliable operation within the specified temperature range.
Part Context
This part belongs to the MP6523 family of motor drivers from Monolithic Power Systems. It serves as a pre-driver stage, requiring external power MOSFETs to handle the main current paths. The GR-Z designation specifies the tape and reel packaging format suitable for automated assembly processes in high-volume manufacturing environments.
Replacement Considerations
The MPQ6523GRE-AEC1-Z is an automotive-grade qualified variant of this series. Verify if AEC-Q100 certification is required for your application. Check for pin-to-pin compatibility and identical electrical characteristics before substituting.
