E-L293DD013TR

Overview

The L293DD013TR is a surface-mount motor driver from the L293D series by STMicroelectronics. It features a push-pull four-channel configuration housed in a 20-pin SOIC package with an exposed thermal pad for heat dissipation. The device supports a maximum supply voltage of 36V and operates within a temperature range of -40°C to +150°C. It provides a continuous output current of 600mA per channel, with a peak non-repetitive current capability of 1.2A. The typical switching frequency is rated at 5kHz, and it accepts standard DTL or TTL logic levels.

Feature Summary

• Integrated internal clamp diodes for protection against inductive load transients
• Separate logic supply input allowing operation at lower control voltages
• Enable inputs for each pair of channels to simplify bridge configurations
• Overtemperature protection circuitry to prevent device damage

Applications

• Brushed DC motor control
• Solenoid driving
• Relay switching applications
• Stepping motor control

Procurement Notes

Verify the specific suffix '013' against the manufacturer's official documentation to confirm the exact reel packaging and tape-and-reel specifications. Ensure that the 20-lead SOIC package dimensions match the target PCB footprint requirements. Confirm that the thermal pad connection strategy aligns with the board design for adequate heat sinking during operation.

Selection Notes

Select this component when a surface-mount solution is required for driving inductive loads up to 600mA continuously. The 20-pin SOIC package offers better thermal performance compared to through-hole variants due to the central pins connected for heatsinking. Consider the 36V voltage rating and wide operating temperature range for robust industrial or automotive environments where high noise immunity is necessary.

Part Context

This part belongs to the L293D family of monolithic integrated high-voltage, high-current four-channel drivers. While the standard L293D uses a 16-lead plastic package, the L293DD variant utilizes a 20-lead surface mount assembly. The L293DD013TR specifically denotes the tape-and-reel version of this surface-mount driver, designed for automated assembly processes.

Replacement Considerations

The L293DD (tube package) serves as the direct pin-compatible alternative if reel packaging is not required. Other L293D family members may offer different package types but share similar functional characteristics.
