L293NEE4

Overview

The L293NEE4 is a quad half-bridge motor driver from the L293D series by Texas Instruments. It operates on a single supply voltage ranging from 4.5V to 36V. The device provides four independent outputs, each capable of delivering up to 1A continuous current with peak currents reaching 2A per channel. Designed for through-hole mounting in a 16-pin PDIP package, it features separate logic and motor power supplies to optimize performance. The component includes internal clamp diodes for inductive load protection and supports operation within a temperature range of 0°C to 70°C.

Feature Summary

• Integrated quad half-bridge architecture enabling bidirectional control of DC motors or solenoids
• Internal clamp diodes provide protection against transient voltages generated by inductive loads
• Separate VCC and VM inputs allow independent powering of logic circuits and motor loads

Applications

• Brushed DC motor speed and direction control systems
• Solenoid driver circuits for industrial actuators
• General-purpose high-current switching applications

Procurement Notes

Verify that the ordering suffix 'E4' corresponds to the specific lead-free and RoHS-compliant variant required for your assembly process. Confirm the package type matches your PCB footprint requirements. Ensure the selected distributor sources directly from authorized channels to guarantee component authenticity and traceability.

Selection Notes

Select this component when designing circuits requiring multiple independent motor channels within a single integrated solution. It is suitable for applications where moderate current levels around 1A are sufficient. Consider thermal management strategies if operating near maximum current limits due to the standard plastic DIP packaging limitations.

Part Context

This part belongs to the L293 family of motor drivers, widely used for driving inductive loads such as relays, solenoids, and DC motors. The L293NEE4 specifically denotes the lead-free version of the standard L293NE, adhering to environmental compliance standards while maintaining identical electrical characteristics and pinout compatibility.

Replacement Considerations

Direct substitutes include the L293NE and L293DNE. Verify pinout compatibility before substitution.
