LB1950V-TLM-E

Overview

The LB1950V-TLM-E is a dual H-bridge motor driver IC manufactured by onsemi. It integrates two independent H-bridge circuits capable of driving DC motors or stepper motor coils in both forward and reverse directions. The device supports PWM control for speed regulation and includes built-in protection features such as thermal shutdown and short-circuit protection to ensure reliable operation under various load conditions.

Feature Summary

• Dual H-bridge architecture enabling independent control of two DC motors or one bipolar stepper motor
• Integrated thermal shutdown and short-circuit protection mechanisms for enhanced system reliability
• Supports PWM input signals for precise speed and direction control

Applications

• Small DC motor control in home appliances
• Bipolar stepper motor drivers in office automation equipment
• Robotics actuator control systems

Procurement Notes

Verify the exact suffix 'TLM-E' against official onsemi documentation to confirm package type and tape/reel specifications. Ensure compatibility with your system's voltage and current requirements before procurement. Cross-reference the datasheet revision date to guarantee access to the most recent electrical characteristics and application notes.

Selection Notes

Select this component when a compact solution for driving two low-power DC motors or a single stepper motor is required. Consider its integrated protection features if operating in environments prone to thermal stress or electrical faults. Verify that the supply voltage range aligns with your system's power rails and that the output current capability meets the motor's stall and running current demands.

Part Context

This part belongs to onsemi's LB1950 series of motor driver ICs, designed for cost-effective and space-constrained applications. The series typically offers integrated logic inputs and high-current outputs suitable for consumer electronics and industrial control panels where reliable motor actuation is critical without external discrete components.

Replacement Considerations

Consult onsemi's official cross-reference tools for verified substitutes. Common alternatives may include other dual H-bridge drivers from manufacturers like STMicroelectronics or Texas Instruments, provided pinouts and electrical ratings are compatible. Always validate functional equivalence through detailed datasheet comparison.
