LB11651H-TLM-E

Overview

The LB11651H-TLM-E is a bipolar motor driver manufactured by onsemi, designed for general-purpose applications. It features a fully integrated control and power stage with a half-bridge output configuration consisting of two channels. The device supports parallel and PWM interfaces for precise motor control. It operates with a supply voltage range of 3V to 5.25V and handles load voltages from 8V to 28V. The component delivers an output current of 3A and is housed in a 36-HSOP package. It is rated for an operating temperature range of -20°C to 85°C (TA) and utilizes bipolar technology.

Feature Summary

• Fully integrated design combining control logic and power stages
• Supports parallel and PWM interface protocols
• Capable of driving bipolar motors with high current output

Applications

• Brushed DC motor driving
• General purpose motor control systems

Procurement Notes

Verify the specific suffix TLM-E against official datasheets to confirm pinout and thermal characteristics. Confirm RoHS compliance status as required by project specifications. Check for obsolescence notices or product change notifications from onsemi prior to finalizing procurement plans.

Selection Notes

Select this component when a fully integrated bipolar motor driver is required for brushed DC applications. Ensure the system voltage aligns with the 3V to 5.25V supply and 8V to 28V load ranges. Verify that the 36-HSOP package fits the PCB layout constraints and thermal management requirements.

Part Context

This part belongs to the LB11651 family of motor drivers from onsemi. The family includes variants such as LB11651-E and LB11651H-MPB-E, which share similar functional architectures but differ in packaging and pin configurations. These devices are categorized under power management ICs specifically for motor control applications.

Replacement Considerations

Direct substitutes include other LB11651 family members like LB11651H-MPB-E, provided the package difference between HSOP and MPB is accommodated. Cross-reference electrical parameters and pinouts carefully before substitution.
