LB11922-TLM-E

Overview

The LB11922-TLM-E is a low-voltage motor driver integrated circuit manufactured by Sanyo (now part of Semiconductors). It is designed for driving DC motors in applications requiring precise control and efficiency. The device integrates power DMOS transistors to handle motor currents directly, reducing the need for external components. It features protection mechanisms such as thermal shutdown and short-circuit protection to ensure reliable operation under varying load conditions. The component is housed in a compact surface-mount package suitable for space-constrained electronic designs.

Feature Summary

• Integrates dual full-bridge DMOS outputs for direct DC motor drive capability
• Includes built-in thermal shutdown and short-circuit protection circuits
• Supports PWM control signals for efficient speed regulation
• Operates with low quiescent current to minimize power consumption

Applications

• Automotive window and seat adjustment motors
• Home appliance fan and pump control systems
• Industrial automation small DC motor drives
• Office equipment actuator control

Procurement Notes

Verify the manufacturer status as Sanyo Semiconductor assets were acquired by ON Semiconductor. Confirm the specific suffix '-TLM-E' matches the required RoHS compliance and packaging type. Check for obsolescence notices or recommended new parts from the current manufacturer documentation before finalizing procurement plans.

Selection Notes

Select this component when a dual-channel low-side or half-bridge configuration is insufficient and a full H-bridge solution is needed for bidirectional motor control. Ensure the supply voltage range aligns with the system's available power rails. Consider the thermal performance requirements based on the expected continuous current load and ambient operating temperature.

Part Context

This part belongs to the family of low-voltage motor drivers designed for consumer and automotive electronics. It represents a transition period component where Sanyo branding was still present before full integration into the ON Semiconductor portfolio. Similar devices in this category typically focus on cost-effective integration of power stages with logic-level inputs.

Replacement Considerations

Check for equivalents from ON Semiconductor, which acquired Sanyo's semiconductor business. Verify pin compatibility and electrical specifications against current active parts in the same voltage and current class.
