L298 Motor Driver

Overview

The L298 Driver is a high voltage, high current dual ful bridge driver designed to accept standard TTL logic levels and drive inductive loads such relays, solenoids, DC and stepping motors. Two enable inputs are provided to enable or disable the device independently of the input signals. The emmiters of the lower transistors of each bridge are connected together the corresponding external terminal can be used for the connection of an external sensing resistor.

L298 MOTOR DRIVER:

Features:

• Operating supply voltage up to 46 V
• .Total DC current up to 4 A 
• .Low saturation voltage
• .Overtemperature protection.
• .LOGICAL "0" INPUT VOLTAGE UP TO 1.5 V (HIGH NOISE IMMUNITY)
• Four motor direction indicator LEDs
• An onboard user-accessable 5V low-dropout regulator
• Schottky EMF-protection diodes
• Screw-terminals for power and motor connections.

4 RELAY INTERFACING BOARD

Overview

The board has four relays driven by ULN2803 IC. The board works on 12V but the input signal can come directly from microcontroller output working at 3V or 5V to control relays. Each relay can switch varierty of AC or DC high voltage, high current loads working at 110V or 220V AC mains like lights, fans, motors and such. The status of relay is indicated by individual LEDs.

4 RELAY INTERFACING:

Features

• LED indication for relay & power supply. 
• Design based on highly proven IC ULN2803 as driver. 
• Direct input from 3-5V micro-controller for relay control.
• High Current (8A) Capability.
• AC or DC Operating Voltages.
• No Leakage Current.
• Eliminates costly isolation relays and wiring.
