Overview
The MC3PHACVDW is a monolithic intelligent motor controller designed for low-cost, variable-speed three-phase AC motor drive systems. It operates on a supply voltage range of 4.5V to 5.5V and utilizes a 28-SOIC surface-mount package. The device supports AC and synchronous motor types with an interface type of serial communication. It functions as a controller for commutation and direction management, featuring pre-driver output configurations consisting of three half-bridges. The component is rated for an operating temperature range from -40°C to 105°C.
Feature Summary
- Monolithic integration of all active functions required for open-loop three-phase AC motor control without software development requirements.
- Volts-per-Hertz speed control capability adaptable to environmental conditions.
- Serial interface for configuration and control operations.
Applications
- Variable-speed three-phase AC motor control systems
- Low-cost industrial motor drives
- Open-loop AC motor applications
Procurement Notes
Verify RoHS compliance status as the component is listed as non-compliant in official documentation. Confirm lead times and availability as the part status is marked as obsolete or end-of-life by the manufacturer. Ensure compatibility with existing 28-SOIC footprints and 4.5V-5.5V power domains during replacement planning.
Selection Notes
Select this component for applications requiring dedicated hardware-based control for three-phase AC motors without microcontroller resources. It is suitable for designs prioritizing simplicity and cost-efficiency over programmable flexibility. Verify that the application does not require complex closed-loop algorithms or software-defined logic, as the device operates via fixed hardware functions.
Part Context
The MC3PHACVDW belongs to the MC3PHAC family of intelligent motor controllers manufactured by NXP USA Inc. This series is engineered specifically for three-phase AC motor applications, offering a complete solution for commutation and direction management. The device eliminates the need for external control logic or software processing, integrating all necessary functions into a single chip.
Replacement Considerations
The product status is listed as obsolete. No specific public substitute part numbers are confirmed in the provided documentation. Engineers should consult NXP official channels for current alternative recommendations or design-in support for legacy replacements.
