LV8731V-TLM-H

Overview

The LV8731V-TLM-H is a Bi-CMOS LSI PWM constant-current control stepping motor driver manufactured by onsemi. It integrates full control and power stages for bipolar stepper motors, supporting resolutions of 1, 1/2, 1/4, and 1/16 steps. The device operates with a supply voltage range of 0V to 5.5V and drives loads between 9V and 32V. It features a 44-SSOPK package with exposed pad for thermal management and functions within an operating temperature range of -20°C to +85°C.

Feature Summary

Integrates PWM constant-current control logic with power output stages
Supports multiple step resolutions including full, half, quarter, and sixteenth steps
Designed for bipolar stepper motor applications with parallel interface

Applications

General purpose stepper motor driving
Motion control systems requiring precise positioning
Automation equipment utilizing bipolar stepper actuators

Procurement Notes

Verify the specific suffix TLM-H against official onsemi documentation to confirm tape and reel packaging specifications. Confirm current availability status as distribution channels may list this component as obsolete or end-of-life. Ensure the ordering part number matches the exact electrical and mechanical requirements for your design implementation.

Selection Notes

Select this component when a fully integrated solution for bipolar stepper motors is required without external power transistors. It is suitable for designs needing PWM current control to reduce heat and improve efficiency at low speeds. Consider the 44-pin SSOP package constraints and thermal dissipation requirements for the target application environment.

Part Context

This part belongs to the LV8731 family of motor drivers from onsemi. It shares core functionality with variants like the LV8731V-MPB-H but differs in packaging and shipping configuration. The family is designed for general-purpose motion control applications requiring reliable stepper motor operation with integrated protection features.
