LV8734V-TLM-H

Overview

The LV8734V-TLM-H is a bipolar stepper motor driver manufactured by Sanyo, utilizing BiCDMOS technology. It operates within a supply voltage range of 9V to 32V and supports a maximum operating temperature of +85°C. The device is housed in a 44-SSOP surface-mount package and delivers a current capacity of 1.75A. Designed for PWM constant current control, it functions as both a motor driver and controller for general applications.

Feature Summary

• Integrates BiCDMOS technology for efficient bipolar stepper motor control
• Supports PWM constant current regulation for precise motor operation
• Compatible with standard surface-mount assembly processes

Applications

• General purpose bipolar stepper motor control systems
• Industrial automation equipment requiring precise positioning
• Office automation devices such as printers or scanners

Procurement Notes

Verify the manufacturer designation, as Sanyo semiconductor assets are often managed by onsemi. Confirm the specific suffix 'TLM-H' corresponds to the required packaging and tape-and-reel specifications. Ensure compatibility with the intended voltage range and thermal management requirements before finalizing procurement orders.

Selection Notes

Select this component when a dedicated bipolar stepper driver with integrated PWM control is required. The 44-SSOP package suits designs needing high pin counts for complex control signals. Verify that the 1.75A output current meets the load requirements and that the 32V maximum voltage aligns with the power supply design.

Part Context

This part belongs to the family of BiCDMOS-based motor drivers designed for compact, high-performance applications. The integration of driver and controller functions reduces external component count. The 44-pin SSOP form factor allows for dense PCB layouts in space-constrained electronic devices.

Replacement Considerations

Check for direct substitutes from onsemi, which acquired Sanyo's semiconductor business. Verify pinout compatibility and electrical parameters against alternative stepper drivers if sourcing from different manufacturers.
