We will thoroughly introduce the L293DD013TR in this manual, including its pinout, features, power supply needs, motor connections, control signals, enable pins, and current sensing. Also, we will offer advice for resolving typical IC problems. This book will teach you everything you need to know about the L293DD013TR and how to use it in your projects, whether you’re an expert or a novice robotics enthusiast.

L293DD013TR Description

The Device is an integrated high voltage, high current, four-channel driver monolithic in construction and intended to drive switching power transistors and inductive loads (such as relays, solenoids, DC, and stepping motors) while also accepting normal DTL or TTL logic levels. Each pair of channels has an enabled input to make it easier to use them as two bridges. The logic has a second supply input that enables functioning at a lower voltage, and internal clamp diodes are also present. This device can be used in switching applications at up to 5 kHz.

The L293D is put together in a 16-lead plastic package, and its four middle pins are used for heatsinking. The L293DD is put together in a 20-lead surface mount that uses 8 center pins for heatsinking and is connected to one another.


A 16-pin dual-in-line (DIP) box houses the L293DD013TR. The IC’s pinout is as follows:

Pin 1: Enable 1, which turns on the H-bridge 1 output. Input 1 on pin 2 directs the motion of the motor attached to H-bridge 1.

Pin 3: Output 1, linked to one of the motor’s terminals via H-bridge 1.

Pin 4: Ground, which is joined to the power supply’s ground.

Pin 5: Ground, which is wired to the power supply’s ground.

Pin 6: The H-bridge 1 output pin, or Output 2, is connected to the other motor terminal. Input 2 on pin 7 directs the motion of the motor attached to H-bridge 2.

Pin 8: Enable 2, which turns on the H-bridge 2’s output.

Pin 9: Ground, which is wired to the power supply’s ground.

Pin 10: Ground, which is wired to the power supply’s ground.

Pin 11: Output 3, linked to one of the motor’s H-bridge 2-connected terminals.

Pin 12: The direction of the motor attached to H-bridge 3 is managed by input number three.

Pin 13: The H-bridge 2’s output number four is connected to the other terminal of the motor.

Pin 14: Vcc2, which is the H-bridge 2’s power supply.

Pin 15: Vcc1, which is the H-bridge 1 power supply.

Pin 16: Vcc, which serves as the IC’s power source.

Four pins comprise each H-bridge: Ground, Input, Output, and Enable. The H-bridge output can be enabled or disabled using the Enable pin. While the Output pin is connected to the motor, the Input pin controls the motor’s direction. The power supply’s ground is linked to the Ground pin.

The required voltage for the IC and the motor is supplied by the power supply pins (Vcc and Vcc1, Vcc2). Each H-bridge is powered individually by Vcc1 and Vcc2, and Vcc is connected to the IC’s power source.

It’s vital to remember that the L293DD013TR’s pinout may differ slightly from other L293D IC iterations. Before attaching the IC to the motor and power supply, it is imperative to review the datasheet.


A dual H-bridge motor driver IC called the L293DD013TR regulates the direction and speed of stepper and DC motors. It employs the H-bridge architecture, enabling it to regulate the polarity and amount of power supplied to the motor. This makes it possible for the motor to revolve in any direction and at different rates.

The L293DD013TR uses two NPN and two PNP transistors in each of its H-bridges. When the input signal is provided, the relevant transistors are turned on due to how the transistors are placed, allowing current to flow through the motor in the desired direction.

The L293DD013TR employs two input pins for each H-bridge to regulate the motor’s direction. The H-bridge can be set up to apply the voltage across the motor in either the forward or backward direction by adjusting the input signals. Each H-bridge on the IC also contains two enable pins that the user can use to turn it on or off.

Pulse-width modulation is a method that the L293DD013TR use to regulate the motor’s speed (PWM). PWM is a technique for regulating the input signal’s on- and off-time to regulate the amount of power sent to the motor. The average voltage applied to the motor can be altered, which changes the speed, by altering the duty cycle of the PWM signal.

Other built-in safety features for the L293DD013TR include thermal shutdown, over-current protection, and under-voltage lockout. These features aid in guarding against damage from excessive current or voltage to the IC and the motor.

The L293DD013TR is an effective and trustworthy motor driver IC that offers precise control over the direction and speed of DC and stepper motors. It is a crucial tool for robotics and other motor control applications because of its H-bridge topology and PWM control.


In conclusion, the highly adaptable and dependable L293DD013TR IC is necessary for motor control applications, particularly in robotics. We have covered its pinout, purpose, mechanism, and special attributes like direction and speed control and built-in safety features.
