- Integrates advanced SMARTMOS technology for enhanced performance
- Supports serial interface communication for configuration and control
Applications
- DC motor current control systems
- Pulse-width modulated motor drive applications
- Industrial automation motor control
Procurement Notes
Verify the specific suffix 'EGR2' against official NXP documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 24-SOIC form factor. Confirm that the 4.5V to 5.5V logic supply range aligns with system requirements before procurement.
Selection Notes
Select this component for applications requiring integrated full-bridge PWM control of DC motors. The SMARTMOS technology offers advantages in efficiency and thermal management compared to discrete solutions. Ensure the design accommodates the 20V to 45V load voltage range and serial interface timing requirements.
Part Context
This part belongs to the MC34923 family of motor drivers from NXP. It is specifically engineered for high-performance DC motor applications requiring precise current regulation. The integration of power MOSFETs and control logic in a single package simplifies system design and reduces component count.
Replacement Considerations
Check for direct pin-to-pin replacements within the MC34923 series or compatible NXP motor driver families. Verify that any substitute maintains the same 24-SOIC package and electrical characteristics, particularly the 4.5V-5.5V supply range and 20V-45V load capability.
