The L297 integrates all the control circuitry required to control bipolar and unipolar stepper motors. Used with a dual bridge driver such as the L298N forms a complete microprocessor-to-bipolar stepper motor interface.

Mounted in DIP20 and SO20 packages, the L297 can be used with monolithic bridge drives such as the L298N or L293E, or with discrete transistors and darlingtons.

The L297 Stepper Motor Controller IC generates four phase drive signals for two phase bipolar and four phase unipolar step motors in microcomputer-controlled applications.

SPICE simulation of a bipolar stepper motor. The circuit implements a controller for a bipolar stepper motor, with an IC controller L297 that generates four phase drive signals for two phase bipolar motor. It requires only clock, direction and mode input signals.

Apr 13, 2008 · L298 is an integrated H-bridge driver. Bipolar stepper motors are designed for driving. Max 2A/Phas could flow. The output signal is applied to the input phase upgrade to serve. That is to say that the step motor (bipolar, has enforced) 4 signals needed to be able to rotate. He owns 2 coils, or without equal, with only 4 wires.

I have paired up L297 and L298 together to make a bipolar stepper driver. My schematics are : I have hooked up the step and direction pin number 4 and 5 respectively on Arduino.

Using L297-L298 integrated circuits manufactured by SGS Thomson (ST) can be made a control circuit for a stepper motor with two phase bipolar or unipolar four-phase (maximum current allowed on stage is 2 A).

The L298 is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads. Two enable inputs are provided to enable or disable the device independently of the input signals.

Aug 18, 2004 · No, INHx are connected to enable bit of L298, and they are outputs of L297. You cannot control it normally. To control these pins, you need CONTROL input to select the mode of control. ABCD is connect to the inputs of L298, to generate pulses on dual H bridge. INH is used to stop the L298.

Sep 12, 2021 · I've made a drive board featuring L297 and L298N stepper motor drivers by the schematics I found online and I'm not sure how to connect everything to the Arduino.
