LB11961-TLM-H-W

Overview

The LB11961-TLM-H-W is a dual DC motor driver IC manufactured by onsemi. It integrates two H-bridge circuits capable of driving two DC motors or one stepper motor in full-step mode. The device supports PWM speed control and direction control via logic inputs. Key electrical specifications include a supply voltage range of 2.5V to 13.5V and a continuous output current of 0.8A per channel. It features built-in protection mechanisms such as thermal shutdown and over-current protection to ensure reliable operation in various embedded applications.

Feature Summary

Integrates dual H-bridge drivers for independent control of two DC motors or a single bipolar stepper motor.
Includes comprehensive protection features like thermal shutdown and over-current limiting to safeguard the device during fault conditions.
Supports direct interface with standard logic families, simplifying system design and reducing external component count.

Applications

Small appliance motor control systems
Portable electronic devices requiring low-power motor actuation
Automotive interior components such as window lifts or seat adjusters

Procurement Notes

Verify the specific suffix 'TLM-H-W' against official onsemi documentation to confirm package type and tape/reel configuration. Ensure compatibility with your system's voltage levels and thermal requirements before procurement. Cross-reference the manufacturer's latest datasheet for any updates regarding pinout or electrical characteristics.

Selection Notes

Select this component when dual low-current DC motor control is required within a compact footprint. Consider its operating voltage range and current capabilities relative to your motor load. Evaluate the need for integrated protection features versus external circuitry based on your application's reliability standards.

Part Context

This part belongs to onsemi's line of motor driver integrated circuits designed for low-power applications. It is engineered to provide efficient control solutions for consumer electronics and automotive subsystems where space and power consumption are critical constraints.

Replacement Considerations

Consult onsemi's official cross-reference tools for verified substitute part numbers. Ensure any replacement matches the original's pinout, voltage ratings, and current handling capabilities without requiring board redesign.

FAQ

Can the LB11961 drive a unipolar stepper motor?

No, the LB11961 is designed for bipolar stepper motors or two separate DC motors. Unipolar steppers typically require different driver configurations.
