PMIC - Motor Drivers, Controllers are one of the most important components for automatic control. The E-L293DD013TR is an important member of this family used for driving two lport motors such as mechanical engineering, robots, electric actuators and unmanned aerial vehicles (UAVs).

The E-L293DD013TR has a few important performance characteristics, such as high speed logic input, flexible demultiplexer and high oscillator frequency. Moreover, it also offers best-in-class performance during continuous operation as well as excellent driving capacity, making it an ideal device for controlling inductive loads and high-voltage operation.

The E-L293DD013TR is programmed specifically for motor control applications, providing a flexible and cost-effective solution for driving a wide variety of motors such as step motor, brushless motor, dc motor and gear motor. It also offers full protection and fault detection to prolong the motor\'s life. Furthermore, its power efficiency is highly optimized to achieve better operation compared to other types, while providing good thermal performance in all conditions.

The E-L293DD013TR is designed with a dual-channel architecture and two independent enable pins, which means that one enable pin can be used to control two enable outputs at the same time, making it possible to perform simultaneous control on two motors, if required. Additionally, the device enables implement bi-directional speed control for more efficient control.

With its integrated logic control, the E-L293DD013TR has a low power consumption of only 11nA, resulting in an extremely low operational cost compared to other types of motor drivers. Furthermore, the device has an IC temperature rating of 70 deg C, supporting it to work in hostile environments and extreme temperature conditions.

In terms of working principle, the E-L293DD013TR is designed to provide bidirectional drive and control for two-line lport DC brush motors. It consists of two H-bridges (which is why it is also referred to as a dual H-bridge driver), and each bridge is capable of withstanding up to 1.2A continuous current for a total of 2.4A of drive current when the two bridges are connected in parallel. The two bridges are controlled by the output enable pin and PWM pin, respectively.

The output enable pin is used to enable or disable both the output power and the PWM pin. When the Enable pin is LOW both outputs are OFF, thus disabling the motors and stopping them. When the Enable pin is HIGH, the PWM pin is used to control the motor speed regardless of the direction of the motor. The PWM pin can be set by the user according to the application, or can be set to the output of either a micro-controller or an external switching circuit.

The E-L293DD013TR features a variety of protection features, such as over-voltage protection and over-temperature protection, in order to ensure reliable and safe operation. Additionally, it has an open-drain flag pin to indicate when the supply voltage is too low or when the current reaches its upper limit. This feature helps to protect the motor from being over-currented and extends the life of the motor.

In conclusion, the E-L293DD013TR is a highly capable motor driver and controller, ideal for use in applications where reliable and accurate control of two motors is required. Its dual channel architecture, high-speed logic inputs and integrated protection features make it both secure and economical.
