L298N

Key datasheet specifications and the closest alternatives, ranked by parametric similarity and grounded in the manufacturer datasheet.

01 — Overview

This datasheet covers the L298N, a dual full-bridge motor driver IC designed for two-phase and four-phase stepper motors. The document details its operation as a high-voltage, large-current driver capable of controlling two 2-phase or one 4-phase motor simultaneously via TTL logic signals. Key parameters include a maximum supply voltage of 36V (up to 38V absolute), continuous output current of 2A per channel, and a low saturation voltage. It features built-in thermal protection and operates with logic levels up to 1.5V. Packaged in ZIP-15/Multiwatt-15, it is intended for applications like electric toys and vending machines.
