L298N

Full Half-Bridge (H Bridge) Drivers Overview

The L298N is a high-voltage, high-current dual full-bridge motor driver manufactured by STMicroelectronics. It operates with a supply voltage up to 46 V and delivers a total DC current of 4 A across two channels, each capable of 2 A continuous output. The device accepts standard TTL logic levels and features an additional power input for lower-voltage logic operation. It includes overtemperature protection and low saturation voltage characteristics within a 15-lead Multiwatt package.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix designation against the manufacturer datasheet to confirm package type and pin configuration. Ensure the component meets RoHS compliance requirements for the intended application. Confirm that the operating temperature range aligns with the system's thermal environment before finalizing procurement.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when a robust solution for driving high-voltage inductive loads is required. The dual bridge design supports independent control of two motors or one stepper motor. Consider the thermal management needs due to the 25 W dissipation capability and the through-hole mounting style for reliable heat dissipation in industrial environments.

Full Half-Bridge (H Bridge) Drivers Part Context

The L298N belongs to the L298 series of motor drivers from STMicroelectronics. It is part of a broader portfolio including variants like the L298HN.
