L298N Motor Driver IC is a high power, dual H bridge driver that can be used to control DC motors, stepper motors, and other inductive loads. It has two independent motor control channels, each of which can provide up to 2A of current and 46V of voltage.
Pin count: 16
Operating voltage range: 5V to 46V
Maximum supply voltage: 50V
Maximum Input and Enable Voltage: 7V
Maximum current allowed to draw through each output: 3A
It is a high voltage, high current, dual full-bridge driver designed to accept standard TTL logic levels (Control Logic) and drive inductive loads such as relays, Solenoids, DC and Stepper motors. Two enable inputs are provided to Enable or disable the device independently of the input signals. The emitters of the lower transistors of each bridge are connected together and the corresponding external terminal can be used for the connection of an external sensing resistor.
Pin Configuration
Pin 1(CURRENT SENSING A) Between this pin and ground is connected the sense resistor to control the current of the load
Pin 2(OUTPUT 1), Pin 3(OUTPUT 2)Outputs of the H- Bridge A. The current that flows through the load connected between these two pins is monitored at pin 1.
Pin 4(SUPPLY VOLTAGE VS)Connected to +5V
Pin 5(INPUT 1), Pin 7(INPUT 2) TTL Compatible Control Inputs of the Bridge A.
Pin 6(ENABLE A) TTL Compatible Enable Input. The LOW state for disable.
Pin 8(GND) connected to GROUND
Pin 9(LOGIC SUPPLY VOLTAGE)Supply Voltage for the Logic Blocks
Pin 10(INPUT 3), Pin 12(INPUT 4) TTL Compatible Control Inputs of the Bridge B.
Pin 11(ENABLE B) TTL Compatible Enable Input. The LOW state for disable.
Pin 13(OUTPUT 3), Pin 14(OUTPUT 4)Outputs of the H- Bridge B. The current that flows through the load connected between these two pins is monitored at pin 15.
Pin 15(CURRENT SENSING B) Between this pin and ground is connected the sense resistor to control the current of the load
