It accepts standard TTL logic level signals and can drive stepper motors with a voltage of 46V and 2.5A per phase or below.Įach bridge has an enable input, which allows or prohibits the device to work without being affected by the input signal. L298 is a high-voltage and high-current dual full-bridge driver with two H-bridges. The phase required by the stepping motor is generated inside the circuit, which greatly reduces the burden on the CPU. A notable feature of l297 is that only clock, direction, and mode input signals are required. The on-chip PWM chopper circuit allows switching control of the winding current.
There are three drive modes: half-step, full-step, and wave. It is suitable for the control of bipolar two-phase stepper motors or unipolar four-phase stepper motors. Standard stepper motor driver using L297 and L298 IC III L297 and L298 Hardware circuit 3.1 L297 Overview
