L293DD013TR

Overview

The L293DD013TR is a surface-mount motor driver from the L293D series by STMicroelectronics. It features four push-pull channels with internal clamp diodes, designed to drive inductive loads such as DC and stepping motors. The device accepts standard DTL or TTL logic levels and includes separate supply inputs for logic and power. Key electrical parameters include a maximum collector-emitter voltage of 36V, an output current capability of 600mA per channel, and a peak non-repetitive output current of 1.2A per channel. It operates within a temperature range of -40°C to +150°C and supports switching frequencies up to 5kHz.

Feature Summary

• Four-channel push-pull architecture with integrated enable inputs for simplified bridge configuration
• Internal clamp diodes included to protect against inductive load transients
• Overtemperature protection mechanism to safeguard the device during operation
• High noise immunity with logical '0' input voltage tolerance up to 1.5V

Applications

• Brushed DC motor control
• Stepping motor driving
• Relay and solenoid actuation
• Switching power transistor control

Procurement Notes

Verify that the specific ordering suffix matches the required tape-and-reel packaging format for automated assembly processes. Confirm that the SOIC-20 package dimensions align with the target PCB footprint and thermal management requirements. Ensure the component meets all necessary environmental compliance standards for the intended deployment region. Cross-reference the manufacturer part number with official distributor catalogs to validate authenticity and availability status before finalizing procurement orders.

Selection Notes

Select this component when a surface-mount solution is required for driving multiple inductive loads simultaneously. The separate logic supply pin allows for operation with lower voltage logic circuits while supporting higher voltage motor supplies. Consider the thermal dissipation capabilities provided by the exposed pad design for heat sinking onto the printed circuit board. Evaluate the 600mA continuous current rating against the specific load requirements to ensure adequate performance margins.

Part Context

This part belongs to the L293D family of monolithic high-voltage, high-current drivers. While the standard L293D utilizes a 16-lead plastic DIP package, the L293DD variant specifically denotes the 20-lead surface mount version. This family is engineered to accept standard logic levels and drive various inductive loads efficiently. The L293DD013TR represents the specific reel-packaged iteration of this surface-mount device.
