KA44169ABVB

Overview

The KA44169ABVB is a single-phase BLDC motor driver manufactured by Nuvoton Technology Corporation. It integrates PWM soft-switching functionality to achieve silent and efficient driving through soft switching of motor current during phase transitions. The device features Auto Phase Control (APC) for automatic detection and adjustment of motor current phases, reducing external component requirements. It supports DC input speed control and operates with 12V or 24V inputs. The IC is housed in a TSSOP14L package measuring 4.4x5.0mm with a lead pitch of 0.65mm, designed for an operating ambient temperature range from -40°C to 105°C.

Feature Summary

• Integrates PWM soft-switching technology for silent and efficient single-phase motor operation
• Features Auto Phase Control (APC) for automatic phase detection and adjustment without dependency on motor type
• Supports DC input speed control interface

Applications

• Home appliances requiring 12V/24V power supplies
• Office Automation (OA) equipment
• Factory Automation (FA) machinery

Procurement Notes

Verify the exact part number suffix against official Nuvoton documentation, as variations such as KA44169A-VB may exist within the product line. Confirm package specifications and electrical ratings directly from the manufacturer's datasheet before integration. Ensure compatibility with the target motor type and voltage requirements specified in the technical data.

Selection Notes

Select this component for applications requiring simplified design through integrated phase control and reduced external components. The APC feature eliminates the need for complex phase detection circuits. Consider the TSSOP14L package size and thermal characteristics for PCB layout. Verify that the 12V or 24V input range aligns with the system power supply architecture.
