The operating temperature range is from -40 °C to + 125 °C. This motor driver offers both excellent performance and reliability.

Working Principle of LMD18400N/NOPB

The LMD18400N/NOPB motor driver is a full bridge power IC with input logic, output getters, and low-side drivers. This device is powered by a single 6V–36V power supply.The LMD18400N/NOPB has two independent channels to control the motor, each of which has its own signal inputs (IN1, IN2, ENABLE). The signal inputs are interpreted by the internal PWM logic and the corresponding low-side driver is enabled.When the signal inputs are high, the corresponding low-side driver is turned on to power the motor and the high-side driver is turned off. When the signal inputs are low, the high-side driver is turned on and the low-side driver is turned off.The LMD18400N/NOPB motor driver also has an enable pin that is used to turn the device on and off. When the enable pin is held low, the internal logic is disabled and the LMD18400N/NOPB motor driver is turned off.

Conclusion

In conclusion, the LMD18400N/NOPB is a full bridge power IC with input logic, output getters, and low-side drivers. It is a motor driver for DC motor control and can handle up to 6A of peak or RMS current and open circuit voltage up to 36V. It is mainly used in the field of motor driving applications such as automobile systems, industrial automation, robotics, aerospace, and consumer home appliances. It has two signal inputs, IN1, IN2, and an enable pin to turn the device on and off. It has the ability to control a variety of DC motors, stepper motors and brushless DC motors.
