E-L6258EATR

Overview

The E-L6258EATR is a dual full-bridge universal motor driver manufactured by STMicroelectronics, realized in BCD technology. It features a PowerSO-36 surface-mount package with 36 pins. The device supports a supply voltage range of 12V to 40V and delivers an output current of 1.2A per winding in continuous mode, with peak start-up currents up to 1.5A. It operates within a temperature range of -55°C to +150°C and includes integrated thermal protection circuitry.

Feature Summary

• Dual full-bridge architecture capable of driving bipolar stepper motors or bidirectionally controlling two DC motors
• High-efficiency phase shift chopping for low current ripple at minimum control levels
• Integrated cross-conduction protection and thermal shutdown functionality
• TTL/CMOS compatible inputs requiring no external recirculation diodes

Applications

• Bipolar stepper motor drive systems
• Bidirectional brushed DC motor control
• Precision microstepping applications
• Industrial automation motor drivers

Procurement Notes

Verify the specific suffix 'ATR' against official STMicroelectronics documentation to confirm tape-and-reel packaging status and exact electrical tolerances. Ensure compatibility with the PowerSO-36 footprint and validate that the 40V rating aligns with system requirements. Cross-reference datasheet revisions to confirm pinout consistency.

Selection Notes

Select this component for designs requiring high-current DMOS switching with integrated protection. The wide voltage range accommodates various power supplies. Consider the thermal performance limits when designing heat dissipation strategies for continuous operation near maximum current ratings.

Part Context

This part belongs to the L6258 family of universal motor drivers from STMicroelectronics. It shares core architectural features with variants like the L6258E but may differ in packaging configuration or manufacturing lot specifications. The family is designed for robust motor control applications using BCD technology.

Replacement Considerations

Direct substitutes include the L6258E and L6258EX series. Verify pin compatibility and ensure the replacement variant meets the required 40V voltage rating and 1.2A continuous current specification.
