LB11981-TLM-E

Overview

The LB11981-TLM-E is a three-phase sensorless motor driver manufactured by Sanyo Semicon Device. It is designed for driving brushless motors without the need for Hall or FG sensors. The device integrates protection circuits including thermal shutdown, current limiting, and low-voltage shutdown. It supports forward and reverse switching and accommodates both single and dual power supply configurations.

Feature Summary

Eliminates requirement for external Hall or FG sensors
Integrates lock detection with automatic recovery or latching modes
Includes comprehensive protection against thermal overload, current excess, and low voltage

Applications

Refrigerator fan motors
VCR capstan motors
Brushless DC motor control systems

Procurement Notes

Verify the manufacturer designation as Sanyo Semicon Device or its successor entities. Confirm the specific suffix -TLM-E corresponds to the required tape and reel packaging format. Ensure compatibility with the intended motor type and voltage levels before integration.

Selection Notes

Select this component for applications requiring sensorless control of three-phase brushless motors. It is suitable where minimizing component count by removing sensors is critical. Evaluate the integrated protection features against the specific operational environment requirements.
