Overview
The L293NE is a quad half-h bridge motor driver from the L293 series, manufactured by Texas Instruments. It supports brushed DC motors and IGBTs with a maximum collector current of 1 A per channel and peak currents up to 2 A non-repetitive. The device operates on a supply voltage range of 4.5 V to 36 V. It features a 16-pin PDIP package for through-hole mounting, with dimensions of 19.8 mm in length and 4.57 mm in height. The operational temperature range spans from 0°C to 70°C.
Feature Summary
- Provides four independent half-bridge drivers controlled by TTL-compatible logic inputs.
- Includes separate logic supply input to reduce power dissipation during operation.
- Features internal clamp diodes to protect against inductive load transients.
Applications
- Brushed DC motor control systems
- Solenoid driver circuits
- Relay driver applications
Procurement Notes
Verify the manufacturer part number L293NE specifically against Texas Instruments documentation to ensure authenticity. Confirm that the component matches the 16-pin PDIP package specification. Check datasheet parameters for output current ratings and operating temperature limits before integration into designs.
Selection Notes
Select this component when driving low-power brushed DC motors or solenoids requiring bidirectional control. Ensure the application voltage does not exceed 36 V and that thermal management accommodates the through-hole package constraints. Consider the separate logic supply feature if noise immunity or lower logic power consumption is required.
Part Context
The L293NE belongs to the L293 family of quadruple half-h bridge drivers. This series is designed for versatile motor and relay control applications. The 'NE' suffix typically denotes the specific packaging and temperature grade configuration within the Texas Instruments product line.
Replacement Considerations
Compatible substitutes include LM293N and L293DNE. Verify pinout compatibility and electrical specifications such as output current and voltage ratings before substitution.
