Overview
The LV88553RTXG is a Brushless DC (BLDC) motor driver integrated circuit manufactured by onsemi. It functions as a controller for commutation and direction management in single-phase BLDC motors. The device supports a maximum output current of 150 mA, with specific operational limits noted at 50 mA for certain configurations. It utilizes a VCT package configuration to facilitate integration into compact motor control applications requiring closed-loop speed regulation capabilities.
Feature Summary
- Integrated controller for commutation and direction management
- Designed for single-phase brushless DC motor applications
- Supports closed-loop motor rotation speed control
Applications
- Single-phase BLDC motor control systems
- Closed-loop speed regulation circuits
- Compact motor driver designs
Procurement Notes
Verify component status prior to procurement as the LV88553RTXG may be classified as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure that the VCT package variant matches the required footprint for existing designs. Request official documentation to validate electrical characteristics against current application requirements before finalizing orders.
Selection Notes
Select this component for applications requiring integrated commutation and direction management for single-phase BLDC motors. Consider the 150 mA output capability when sizing power stages. Evaluate the VCT package constraints for PCB layout. Verify compatibility with closed-loop control architectures. Assess supply chain stability given potential obsolescence status compared to newer generation drivers.
Part Context
This part belongs to onsemi's portfolio of motor drivers and controllers specifically targeting brushless DC motor applications. It serves as a specialized solution for single-phase configurations, distinguishing itself from multi-phase drivers. The device integrates essential control logic to simplify system design by handling commutation sequences and directional control within a single IC form factor.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided data. Consult manufacturer resources for cross-reference information if direct replacement is required due to obsolescence.
