Features of LB1838JM-TRM-E

The main features of LB1838JM-TRM-E are as follows:

• Embedded current control system enables easy setting of motor speed and smooth rotation
• High degree of integration with built-in functions for current control, PWM, and overcurrent protection, as well as built-in direction control and soft start functions
• Built-in circuit for the detection of current conduction without the need for shunt resistors
• Low current consumption of 0.2 mA (max)
• Compact, space-saving 16-pin QFN package

Working Principle of LB1838JM-TRM-E

LB1838JM-TRM-E has a built-in current control system, consisting of a PWM generator and a MOSFET driver. The current is controlled by changing the pulse width of the PWM signal. The higher the pulse width, the more current is supplied to the motor, resulting in a higher motor speed. Conversely, the lower the pulse width, the lower the current supplied to the motor, resulting in a lower motor speed.

LB1838JM-TRM-E also has built-in functions for overcurrent protection, direction control, and soft start. The overcurrent protection function helps protect the motor and the circuit itself from damage caused by excessive current. The direction control function allows for precise control of the motor\'s direction, while the soft start function prevents sudden acceleration at startup.

Conclusion

LB1838JM-TRM-E is a three-phase motor driver integrated circuit developed by ROHM. Its built-in current control system enables precise control of motor speed and direction, and its built-in overcurrent protection, direction control, and soft start functions enable it to operate safely and reliably. Its wide range of applications and low current consumption make it an ideal choice for motor control in a variety of fields.
