- Supports multiple step resolution modes including full, half, and quarter stepping
- Features high-voltage tolerance for load circuits up to 35V
Applications
- General purpose stepper motor control systems
- Cooling fan motor drivers
- Industrial automation motion control
Procurement Notes
This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution channels indicate limited or no availability in many regions. Verify current stock status with authorized distributors before design finalization. Consider lifecycle management strategies due to discontinued status.
Selection Notes
Select this part for bipolar stepper motor applications requiring integrated control and drive capabilities. Ensure the system load voltage falls within the 9.5V to 35V range and logic levels match the 2.7V to 5.5V specification. Evaluate thermal performance given the 1.5A output capability in the SSOP package. Confirm interface compatibility with parallel control signals.
Part Context
The LV8741VL-TLM-E belongs to the LV874x series of stepper motor drivers from onsemi. This series is categorized under Motor / Motion / Ignition Controllers & Drivers within the PMIC product line. It shares architectural similarities with other devices in the LV873x and LV877x families, focusing on integrated solutions for general-purpose motor control.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, alternative components must be identified through independent cross-reference tools or manufacturer recommendations for new designs.
