- Optimized thermal efficiency in a compact surface mount package.
Applications
- Stepper motor driver applications
- Two-phase motor control systems
Procurement Notes
Verify the manufacturer designation carefully, as this component was originally developed by Sanyo Denki and later associated with onsemi through corporate restructuring. Confirm that the specific suffix TLM-E matches the required surface mount packaging and lead-free compliance specifications for your assembly process before finalizing procurement orders.
Selection Notes
Select this component when a low-voltage operation between 2.5V and 7.5V is required for driving small bipolar stepper motors. The 800mA output current rating suits light-duty applications. Ensure the surface mount footprint fits the PCB layout constraints and that the thermal performance meets the system's heat dissipation requirements within the specified temperature range.
Part Context
This part belongs to the LB1848M series of dual-channel motor drivers. These ICs are specifically engineered for low-voltage environments where minimizing power loss across the driver is critical. The series supports bidirectional operation, making it suitable for controlling standard two-phase stepper motors commonly found in precision positioning equipment.
Replacement Considerations
The LB1846M-TLM-E is a related variant within the same family. Verify if the alternative model meets the specific current and voltage requirements of the application before substitution.
