LB11683H-TLM-E

Overview

The LB11683H-TLM-E is a three-phase full-wave current-linear-drive motor driver IC manufactured by Sanyo Semicon Device. It adopts a sensorless control system that operates without Hall sensors, enabling the driving of both AC and DC motors. The device is housed in a 28-pin HSOP-HC EP package with an exposed pad for thermal management. Key electrical characteristics include a maximum output current capability of 1.5A per phase and operation within a specified voltage range suitable for various motor applications.

Feature Summary

• Sensorless control architecture eliminating the need for external Hall sensors
• Three-phase full-wave current-linear drive topology
• Integrated design supporting both AC and DC motor types
• Thermal performance enhanced by exposed pad package

Applications

• Brushless DC (BLDC) motor drives
• Three-phase AC motor control systems
• Sensorless motor positioning applications
• Compact motor driver modules requiring miniaturization

Procurement Notes

Verify the manufacturer source carefully as Sanyo Semiconductor assets were acquired by onsemi. Ensure the part number suffix matches the specific tape-and-reel or tray configuration required for your assembly line. Confirm the datasheet revision date to ensure compatibility with current design specifications and regulatory standards.

Selection Notes

Select this component when a sensorless solution is preferred to reduce system cost and complexity. The linear drive characteristic offers smooth torque control compared to square-wave alternatives. Consider the thermal requirements of the HSOP-HC EP package for high-current continuous operation scenarios.

Part Context

This integrated circuit belongs to the family of three-phase motor drivers designed for compact electronic devices. It replaces discrete transistor solutions by integrating gate drivers, protection circuits, and the power stage into a single chip. The sensorless feature distinguishes it from models requiring feedback signals for commutation.

Replacement Considerations

Check for direct equivalents such as the LB11683V-TLM-E if pinout or specific current ratings differ slightly. Verify compatibility with existing PCB footprints and thermal vias before substitution.
