LV8746V-TLM-E

Overview

The LV8746V-TLM-E is a Bi-CMOS LSI PWM constant-current control stepping motor driver manufactured by Sanyo (now onsemi). It operates within a supply voltage range of 9.5 V to 35 V and supports a maximum output current of 1.2 A. The device is housed in a 44-pin SSOP package with dimensions of 15 mm x 5.6 mm x 1.5 mm. It functions across an operating temperature range from -20 °C to +85 °C.

Feature Summary

• Implements PWM constant-current control for precise stepping motor regulation
• Integrates Bi-CMOS LSI technology for efficient signal processing

Applications

• Stepping motor control systems
• Precision positioning applications

Procurement Notes

Verify the manufacturer designation, as Sanyo Semiconductor operations were acquired by onsemi. Confirm the specific suffix '-TLM-E' corresponds to the required tape-and-reel packaging format and RoHS compliance status. Ensure the component matches the 44-pin SSOP physical footprint and electrical specifications provided in official datasheets before integration.

Selection Notes

Select this component when a dedicated stepper motor driver with integrated PWM constant-current control is required. It is suitable for designs needing a single-chip solution for motor drive logic and power stages. Consider the 44-pin SSOP package constraints and the 1.2 A current limit relative to the target motor's requirements.

Part Context

This part belongs to the family of Bi-CMOS LSI stepping motor drivers designed for compact and efficient motor control applications. It represents the transition period where Sanyo semiconductor products are often referenced under the onsemi brand following corporate acquisition.

Replacement Considerations

Check for direct equivalents such as the LV8741V-TLM-E, which shares similar packaging and interface characteristics but may differ in specific electrical ratings or feature sets.
