E-L9935013TR

Overview

The E-L9935013TR is a two-phase stepper motor driver circuit manufactured by STMicroelectronics, designed for driving bipolar stepper motors. It features an integrated DMOS technology and accepts control via a Serial Peripheral Interface (SPI). The device operates within a supply voltage range of 8 V to 24 V and supports an output current of 1.2 A. It is housed in a PowerSO-20 surface-mount package and is rated for junction temperatures between -40°C and +150°C.

Feature Summary

• Integrated SPI serial interface for simplified digital control
• DMOS half-bridge architecture for efficient power switching
• High thermal stability suitable for demanding environments

Applications

• Bipolar stepper motor drive systems
• Industrial automation controllers
• Automotive motion control applications

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging configuration when sourcing. Confirm that the component falls under the analog MEMS sensors termination notification PTN ANALOG MEMS SENSORS/25/15347 issued by STMicroelectronics International N.V., which may impact long-term availability or lifecycle status. Ensure compatibility with existing SPI bus protocols before integration.

Selection Notes

Select this component when a robust, high-temperature capable stepper driver with serial interface is required. The PowerSO-20 package offers a compact solution for space-constrained designs. Consider the 1.2 A output capability and 24 V maximum supply voltage against load requirements. Verify that the system architecture supports SPI communication rather than parallel STEP/DIR signals if those are the only available options.

Part Context

This part belongs to the L9935 family of stepper motor drivers from STMicroelectronics. The base L9935 device provides two-phase drive capabilities using DMOS technology. The E-L9935013TR variant specifically denotes the commercial grade version packaged in a PowerSO-20 format, optimized for surface mount assembly processes in modern electronic manufacturing.
