Overview
The LV8726TA-NH is a stepper motor pre-driver manufactured by onsemi. It serves as the control interface for external power MOSFETs, enabling precise management of bipolar and unipolar stepper motors. The device supports high-resolution microstepping up to 1/128 steps through internal logic processing. It integrates features such as current control timing adjustment and protection mechanisms to ensure reliable operation in various industrial applications.
Feature Summary
- Supports microstepping resolution up to 1/128 steps for smooth motor motion
- Functions as a pre-driver for external power MOSFETs in bipolar and unipolar configurations
- Includes built-in protection features for enhanced system reliability
Applications
- Industrial automation systems requiring precise positioning
- Office automation equipment such as printers and scanners
- Medical devices needing controlled motor movement
Procurement Notes
Verify the complete part number including the suffix NH when ordering. Confirm that the application design accommodates external power MOSFETs as this component acts only as a pre-driver. Check datasheet specifications for operating temperature ranges and supply voltage requirements to ensure compatibility with the target system environment.
Selection Notes
Select this component when a dedicated pre-driver is needed to control external power stages rather than an integrated driver IC. Consider the required microstepping resolution and the need for external MOSFET selection based on load current. Evaluate thermal management strategies for the external power components since heat dissipation is handled outside this package.
Part Context
This part belongs to the LV87xx series of stepper motor drivers from onsemi. It is related to other models like the LV8727 and LV8728 which may offer integrated power stages or different feature sets. The series is designed for applications requiring reliable stepper motor control with varying levels of integration.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs before considering alternative pre-drivers from other manufacturers.
