L293DNEE4

Overview

The L293DNEE4 is a quad half-bridge motor driver manufactured by Texas Instruments, designed for brushed DC and stepper motor applications. It features four independent channels capable of delivering up to 1 A continuous output current per channel, with peak currents reaching 2 A non-repetitively. The device operates within a supply voltage range of 4.5 V to 36 V and includes separate logic and motor power supplies to optimize performance. Packaged in a 16-pin PDIP, it incorporates thermal shutdown protection and high noise immunity inputs.

Feature Summary

• Quad half-bridge architecture providing independent control for four channels
• Integrated thermal shutdown circuitry to prevent damage during overheating
• Separate logic and motor power supply inputs for efficient operation
• High noise immunity input stages ensuring stable signal reception

Applications

• Brushed DC motor speed and direction control
• Stepper motor driving in automation systems
• Relay and solenoid switching circuits
• Robotics motion control platforms

Procurement Notes

Verify the specific ordering suffix 'EE4' against the manufacturer's official documentation to confirm package type and environmental compliance status. Ensure that the required output current does not exceed the 1 A continuous limit without adequate heat sinking. Confirm that the application environment remains within the specified operating temperature range to maintain reliability.

Selection Notes

Select this component when a robust, through-hole solution is required for driving multiple motors or loads independently. It is suitable for designs needing high noise immunity and built-in thermal protection. Consider alternative packages if surface-mount space constraints exist, as this part utilizes a PDIP form factor.

Part Context

This device belongs to the L293 series of motor drivers from Texas Instruments. It is functionally compatible with other variants in the family, such as the L293D, offering similar electrical characteristics. The series is widely recognized for its versatility in controlling inductive loads and motors in various industrial and consumer electronic applications.

Replacement Considerations

The L293DNE is a direct functional equivalent within the same product line. Verify pinout compatibility and thermal performance requirements when substituting.
