KA44169A-VB

Overview

The KA44169A-VB is a single-phase BLDC motor driver manufactured by Nuvoton. It integrates Auto Phase Control (APC) and PWM soft-switching to enable silent, efficient operation. The device supports DC input speed control and operates within a wide voltage range of 12V or 24V. It functions reliably in ambient temperatures from -40°C to 105°C. The component is housed in a TSSOP-14L package measuring 4.4x5.0mm with a 0.65mm lead pitch.

Feature Summary

Integrates Auto Phase Control (APC) for automatic phase detection and adjustment, reducing external component count.
Implements PWM soft-switching technology to minimize noise during phase switching for silent motor operation.
Supports DC input interface for straightforward speed control applications.

Applications

Home appliances requiring quiet motor operation
Office automation equipment
Factory automation machinery

Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation to ensure correct package and temperature grade specifications. Confirm availability status through authorized distributors as supply conditions may vary. Cross-reference the datasheet revision date to ensure compatibility with current design requirements and regulatory standards.

Selection Notes

Select this driver for single-phase BLDC motors where low acoustic noise is critical. The integrated APC feature simplifies design by eliminating manual phase alignment. Ensure the application voltage matches the 12V or 24V support range. Consider the TSSOP-14L package dimensions for PCB layout constraints.

Part Context

This component belongs to the KA441xx series of single-phase motor drivers from Nuvoton. It shares functional similarities with models like the KA44168A-VB but offers specific integration levels for APC and soft-switching tailored for efficiency and noise reduction in compact motor control systems.
